I had one too. When I first shot the SIG, I thought, here we go agin.....Just like the original M&P. an Apex bbl fixed that M&P. I no longer have that gun but do have a 9mm and .40sw M&P 2.0 and they are very accurate out of the box.

When I first started analyzing the issues I thought my barrel had some play in the slide by pushing down on it. After careful inspection of this it was actually pushing the slide back slightly when I did this witch resulted in the barrel starting to cam downward. Wasn't anything wrong there. But all that free vertical play, more up front than in the back just struck me as wrong. After some careful measuring I was pretty sure it was a tolerance issue with the FCU shell as it was stamped at the factory. These stamped FCU housings are not the most precise pieces and rely on the dies that strike them for their tolerances. I think SIG needs new dies. Or better yet offer a CNC machined FCU to better control and tighten this up. The FCU housing is amazingly simple. A good CNC machine could spit one out in no time.

Well, I fixed it. Its as good as most of my competition guns now. I decided to do some side to side comparisons with other P320's and a couple M&P's. All of which shot much better than my XFive. In a nutshell my conclusion was that barrel to slide was as good but the way the slide rested in the FCU was so much worse with the XFive. Even with my M17 top end on it there was excessive play. If you pinched the front of the slide to the dustcover there was .032 of free play. Considerably more than any of my other Poly pistols. I had read in another thread about this I believe. I figured the worse I could do was trash an FCU.......down to the workshop (where the big hammers live) and did some swinging. First I took some measurements of the FCU so I could gauge my progress. I needed to lower the rails by .020. At least that was my goal and wanted to approach this number with caution and slowly. It took some real good taps, with the help and trust of my son holding the FCU. But I got er done, and didn't break it. The process widened the rails so they had to be massaged with a file to get a good fit with the slide. I progressed until it was sorta a hard fit then stopped, lubed and re assembled. It actually was like the original Fives in as much as if you rode the slide home it would stop short but released from slide lock went home nicely. Took it outside to my range and it ran flawlessly, and grouped about one third the size as previously and best of all...no flyers at all. First target was a group under 2" Next target was 50rds rapid fire as fast as I could pull the trigger......3-1/4" group. When I tried that last weekend 1/4 of the hits were off the 8x11 paper.

No not the same here. 147's were the most accurate, but not great. Not in my case, I do not shoot coated or plated. All test ammo was FMJ either reloaded or factory loaded. The only ammo my P320 X5 shot remotely accurate was 147 FMJ factory loads. This particular SIG reminds me of the issues I experienced with an early M&P. Ended up being an early unlocking problem. This may be similarly a locking issue. The barrel does depress an unusual amount when in battery. My P320 M17 doesn't budge. The M17 is very accurate with any ammo. The slide and barrel may well both contribute to the problem. It is a real problem, just not sure I am willing to go any further by throwing more $$$ at it. Shame on SIG for a swing and a miss on this dog.

Mines NOT a Legion. At least I was led to believe its not? Its a X5 exchange kit with a TXG grip module. Does SIG make slides that are different for each or the same for both? I would have been very happy were the accuracy as good as my M17. My P210 Target is exceptional and its a production gun. Even my M&P 2.0's (a 9mm and a 40) run circles around this thing with regards to accuracy.

SIG can make accurate guns. I am just flustered that many X5's, a competition gun that was an accurate gun, is now a pile of dung without having to throw more $$ at it and crossing your fingers it gets better. Im tempted to swap slide assemblies with my M17 and see what happens. My M17 is far superior in its ability to shoot accurately. Ive read all the threads about the X5 issues. Mine is one of the several that seems to prefer 147's. There were other posters who's gun favored them also. My M17 likes everything and my 124's shoot great. Same ammo that shoots 1-1/4" groups in it were almost 6" in the X5.

I mean really SIG, Did you forget the formula to provide an accurate pistol? I have an enviable number of SIG Pistols, and have been shooting them for years. Had an original German SIG X5 L1 that was exceptionally accurate. And almost a dozen more that are very accurate. A P210 Target that shoots in my hands 1-1/2" groups, an M17 with RMR that does about the same, A P220 Legion 10mm that will hold its own with them and an AXG and P226 Legion, yup, very accurate pistols. Recently put together a P320 X5 TXG with a Romeo2. That Dogs a heap of %&#^. Only thing comes close to a reasonable group are 147gr factory loads and they are still double the size of any other of my SIGS. Read the thread on the X5 Legion accuracy problems. Also read many threads of SIGS much newer than most of my others with less than stellar accuracy. It seems theres a time period in the last few years that something changed at SIG. Anybody else have any experiences good or bad with SIG and a date of Manufacture regarding accuracy of their production guns?

I just had to try one in my SBR. It was already set up with a TACCOM buffer and it already was somewhat soft, but not even close to my JP-5, but my SBR was softer shooting than my Sons PCC that is running a standard buffer with no weight in the carrier. The Scheel was easy to install and I have started with the recommendation in the literature for 124 factory ammo. Shot about 50 rds and it is softer than with the TACCOM buffer. It falls just about in-between where it was and the JP-5. I didn't think it would be close to the JP-5. I plan to play more with the springs after break in, but so far its been a positive experience. My SBR is a side charger, and initial charging needed to be somewhat brisk, but after hand charging it a few times and a box of ammo, I either got stronger or it smoothed out. My only nit pick is I wish the rollers were black DLC coated. Those shiny silver orbs stick out like a lighthouse in the fog.

The 124's were my standard 9mm loading at 1050 fps for 130 pf. My CZ orange groups 1-3/8" as does my APEX barreled M&P and those are with irons sights. The JP-5 makes one raged hole about an inch in diameter at 25yds. My X-5 with 124's wont even keep 5 bullets in the head box of an IPSC target at 15yds. Then switch to 147's at 139PF and the X5 makes groups (15yds) at about 1-1/2" with an optic. It was also remarkably softer shooting with 147's. This is with the 14lb spring.

I am happy to hear the 147 were softer than 124's in the JP-5. I have only used 124 up until now and they are pretty good. Problem is I like to use the same ammo in both my PCC and pistol. I just got a new SIG X5 and it hates 124's, my groups looked more like a shotgun pattern. 147's on the other hand were nice tight groups. Im looking forward to trying 147's in my JP-5. Was the accuracy any different with 147's in your JP-5?

I started off with a MRO with the circle dot. I had no issues with parallax like some complain about. Now Using a Holosun AEMS with circle dot. The widow is huge by comparison to the MRO. More Eotech like. Im liking it a lot.

In my experience the barrel/ammo and a good trigger will probably get you where you want to be. It is rare that I have put together an AR using a Good barrel (JP, Criterion, BSA, Proof research, Wilson, to name a few) and not gotten sub MOA out of the AR. I never do much special other than ensuring the assembly is done properly. If your chasing accuracy under 1/2 MOA, you may either get lucky with an exceptional barrel/ammo combo, or you will need to resort to more tricks than just the hobbyist typically has the resources for.

I too do not trust the scope to be 100% true with respect to the crosshairs being perfectly oriented. One trick I use is having the rifle perfectly leveled in the vice and the scope leveled to the rifle, I have a door jamb about 40' away that I have verified as being plumb. I look thru the scope to verify the vertical crosshair lines up perfectly with the door jamb while the rifle is perfectly level, and scope has been leveled to the rifle. Sometimes its not. Another trick, on some rifles it's near impossible to get the little level on the rifles rail in such a position to actually view it accurately. I use a little piece of 1/4" Thick x 1" Wide aluminum bar 3" long. I lay it on the rail under the scope with it sticking out just far enough to get the level on. Works perfectly. I do use feeler gauges as well in conjunction with levels (when possible). usually unnecessary, but it is a secondary check to verify my work. The door jamb never moves or gets lost, and the aluminum bar was free. Just like this advice!

I chose the Techwell because I did not find anything else at the time. Im very happy with it though. It fits extremely snug, as in no wiggle or movement at all.. Which I am extremely happy about. I have no idea what the fit is like on the Taylor. I like the really tight fit as I used an Arrendondo on an AR15 for a long time. It was secure but there was a little movement. When I finally removed it, the finish was gone everywhere it touched the receiver. I'm certain this was due to the movement slowly grinding away at the anodizing. Rest of the receiver looked perfect.

Yeah, minimally concussive is a big window. I suppose it's just a matter of how much you're willing to put up with. Set up, technique and bodies aside, the Hypertap will clear ammo boxes and spent cases off the bench. (I can only imagine RO'ing for someone shooting one) My JP has never done that and going back and forth with the same gun and the two muzzle devices has shown no advantage in my case. So I choose the JP for my game gun and leave the Hypertap to other guns. I actually have 3 of each on different rifles/carbines. I have tried others and it's the only rear blasting comp I've decided to keep. Just not on my 3-gun rifle. A friend of mine has the area 419 break on his AR. Its kinda in between. Almost as much blast as the Hypertap. Edited to add: And just yesterday we were doing some sight in work here at my range. My son took a few shots (Hypertap) and something flew right by my face. I was about 4 ft behind him to the right. I looked around and didn't see anything. Thought it was my imagination. when we were packing up I went to re install my turret caps on my Razor and one was MIA.........oh crap, that's what flew in front of my face. Found it about 15 ft away. Lol

Of the rear gassing brakes Ive tried, the Hypertap is good. I stick to my JP comp for my game gun though. I am not a fan of the distracting concussive nature of the Hypertap. Side by side I can tell no difference in shooting performance, but I need to blow my nose after shooting the Hypertap.

20 pages to remind me why I seldom come to this forum any longer. Shameful all the back and forth, name calling and general denigration of others. I say let it be provisional. It will either be well received or it will die. If it kills another division, well, "Only the strong survive".

This part of your post I found most relevant. It meshes perfectly with my disdain for the "Level the playing field" mouthpieces. Its the same ones. When I was learning this sport, leveling the playing field meant go home and practice, analyze your past performances and do whatever it takes to get better. Any complaints I had were self focused.

Under the ejection port directly right of the serial number it will be marked "Remington V3" Additionally it is chambered for up to 3" shells and so marked on the barrel (Hence the V3 model designation). The Versa Max is chambered 3-1/2" and marked accordingly. The slightly smaller and lighter size of the V3 is what attracted me to the V3 over the larger Versa max.

Hi Kurt, hope you're well. Keep an eye out for them. I emailed Remington and this was their response: "Thank you for contacting RemArms, LLC. Our focus is to get the model 870, model 700, model 1100, V3, and Versa Max firearms back to regular production levels. RemArms will continue to evaluate opportunities to bring back other previously produced firearms models as manufacturing capability and capacity improves." Still Lovin my V3. It has none of the quirks my Benelli(s) had.

My V3 has been superb. I hope they release more of them in the future. I want another one for my son.

When you think about it, the JP5 locking piece is also a MP5 clone. Like changing a bolt on any gun, JP is simply stating manufacturing tolerances dictate checking headspace would be prudent. Probably more so with H&K clones as their tolerances may not be up to the standards of H&K and JP.

I really don't have an opinion one way or the other for the vertical comp. It looks cool, and in typical JP fashion is blended seamlessly with the barrel. I don't really feel they do a lot on a 9mm. The way the dot moves is best described as a bit of wiggle. It doesn't do the climb, dip or bounce like other guns. on 6" plates on my star at 15yds the dot doesn't come close to leaving the plate. I think that's more of a testament to how light the bolt is. I have heard others who claim the dot dips with their JP5. I have not noticed that effect. I think how one grips the gun has more to do with it than the muzzle device does, with a PCC.

I started PCC with a blowback Glock mag AR9. Did all the obligatory stuff like Taccom buffer, comp, carrier weight and springs. Got it pretty soft but still more bounce than I liked, but it worked. Didn't really feel like it was holding me back. I had entertained an MPX, but just too much baggage between generations and such I was hesitant. Then the JP5 was announced and were unobtainium for a while and fell off my radar. Then about two months ago, got an email from one of my vendors they had one in stock.......only one! I couldn't log on and break out my credit card fast enough. First shots down range were........wow. I shot my blowback 9 first then immediately switched to the JP5. Let my son do the same. The smile on his face must have been similar to mine. Was shooting my standard 124gr load at 1050fps. As is my habit (bad or good) I immediately added a Magwell, changed furniture, and got rid of the awful mkIII hand guard and installed the JP MLock handguard. Total weight as pictured is 6lb-14oz. Worth every penny to me.

For single stage 3-gun trigger the original JP is hard to beat. I use this for matches weighted to close stages. 2-stage, my favorite for 3-gun is AR-Gold. I prefer this for matches weighted to long distance. General purpose trigger.....LaRue MBT-2 is the best $79.00 trigger out there.
