4x 45⁰ ports. 147gr @ 915fps in the pic. It's pretty silly actually. Effective even at minor pf. This was the comp I posted on the previous page. Baffle surface area is king. Downside of porting is the velocity drop depending on location and amount. Not a fan of holes on the lands either. If that was my only option, I would incorporate the slide holes with the barrel ports to increase their effective length. Just an idea.

It does make a difference even at 130pf. It's not game changer level, but an advantage.

Nice to hear that Rocky was comp friendly (as the rule is written). Working this up for that match this year. Now to convince my AC of the same.

Production 54pts 6.27 8.612hf 100% Shot stationary on both ends.

Getting some practice in for Bianchi. Step one, confirm zero. 1.53" at 50m. That's a personal best.

This topic isn't dead! Lol. I'm going to order some 145gr bullets to test. I have a universal with test barrel but can also borrow an actual barrel fixture. I will go for 1:20. More research on that before I order though. Thanks for all the stories and stuff.

100gr sintered at 1275fps.

All very good points. I think the recoil difference maybe the nail in the coffin. As much as I don't want it to be. I nearly won the Practical stage at Bianchi last year with a 478... turned into a 468 due to a skidder. I took a picture of the target and it still haunts me. The sight time during recoil recovery really makes sense since I lost it by .25 second. Thank you guys for the discussion.

My lead is built into the rear sight, but with my 9mm it's a bit less as I shoot 100gr at 1250. I have the room in the rear sight to account for more lead (slower bullet) which is why I started to consider 45 again. Thanks for posting the numbers ffl as it is definitely something to consider. Also, bullet drop. Rob missing 1920 by .25" is exactly why I'm considering 45. I'm not quite at his level, soooo build a better mousetrap. But is it? That's why I posted here. If I can build it to hold 2" at 50 (which is what I can do with my 9), and recoil wasn't a concern is there anything else to consider? Before I sink of bunch of coin in a test bed, I'll source the projectiles I want to use and shoot them through a test fixture. IF they perform well I may build it just to see. I still have some time... Barrel twist. Thinking lighter, faster loads should I consider a 1:18 or 1:20?

I'm thinking about building a 45acp for Metallic. I haven't been around long enough to know "why" 9mm is king. Recoil, drop at 50, mover event. Anything else? My 9mm is plenty accurate, with the right ammo is stupid soft, but I can't get the "bigger hole" out of my head. Maybe I just want to do it, for the sake of doing it. I'm thinking 140-165gr projectiles at 900fps. I like sintered metal projectiles for accuracy. Anything else to consider?

Anilson, are you going to stock the hinge triggers also? Have you installed a Vario yet? I find them very easy to install. I really don't like working with the SV, especially after installing a few of these.

Gunsmith fit wasn't bad to install. Mine likes light, fast bullets. I did a bunch of work to the factory barrel while I waited for the Apex to show up. Best group was still over 2 inches at 25. Apex gunsmith fit, 1.07" at 25. I was very impressed. 4.11" at 50, but a flier ruined what could have been a great group (shot standing). It will also keep them in the A zone at 100y too.

I would send the gun and barrel to Apex. Something is not right.

Once again, IDPA rules blow my mind. I can change the 320 grip module faster than I can change the backstrap on an M&P. Yet it's "not readily replaceable"? I use grip tape now anyway (M&P).

Did you forget to reassemble with the smaller coil spring? (striker return spring). Take slide off, look at striker foot (pull back until firing pin block catches striker if needed). You should see a coil or two of the return spring.

I am much more likely to hit the -0 or -3 perf than a no shoot perf. I like your first option. Make it the major of 1911 division.

Given equal pf, the advantage goes to the .45. Larger scoring diameter. I shoot .40 180gr at 170 pf and .45 185gr at 170pf. Both feel very similar. I would shoot 40 in CDP because of the brass is easier for me to get.

Fedbizops posted, FBI picked Glock over Sig 320 (and others)...and then there's that. No idea why yet. Just posted yesterday.

TR. I've fired quite a few that had really bad double clicks. Only in dry fire can you notice it. Usually worse with an empty mag installed. It can be fixed. Also, even with the worst one I was not able to induce a failure to reset malfunction. I tried. Hard. Couldn't get it to fail. Back on point: Got out to 50yards this weekend. Standing unsupported, M&P 5 shot group of 4.11". The group of 4 was awesome (1.80") but one round opened the group up to just over 4". Of course it's on video....lol. Youtube....

There are several threads on here about our successes with the Apex barrel. My best rested group at 25y is 1.009" 5 shots. Freestyle is 1.78". Even got out to 50y this weekend, 4.11" 5 shot group while standing unsupported (freestyle). I have well over 1000 rounds through with zero malfunctions. At matches, I'm the guy telling everyone with an M&P "you need an Apex barrel". Ammo used is factory 100gr Frangible at 1275fps.

I was just talking about hr monitors last week. For matches I shoot better juiced up (adrenaline), to a point. I know my hr must soar during the stage. At least I think so. What I want to see is if my hr is higher BEFORE the stage, then actually lowers during. I do full speed walk throughs as the on deck shooter so my hr would be elevated prior to shooting. The other reason it came up. I was group shooting last week and actually felt my hr drop just before I broke each shot. After the shot it sped back up. I double plug and I can both feel and hear my hear rate while shooting. Now I want to see if I can capture it using my garmin and hr monitor. I've never experienced it before. Also shot the best freestyle 25y group of my life.

There are some Q5's on there now, no reserve. They will likely go up over $550.

Wow. The LE price isn't even mid 400's.

Yep. The best stock trigger for Striker guns. Just a trigger spring from being amazing.
