@rlapid216 I do not know what the weight difference is, if there is one, between the TXG grip weight and the standard XFive grip weight. I apologize but right now I do not want to risk goobering up either grip by pulling them out to weigh them. 1) Visually, they are the same shape. 2) The TXG weight is silver in color while the weight in my standard XFive has a very light copperish tone to it. 3) Neither weight is magnetic. I mention that because I remember reading somewhere that one or more people think the weight in the standard XFive is steel.

Thank you for sharing the secret code

@BallisticianX thank you for sharing your experience with the Apex kit in the P320. Are you familiar with the performance of the Apex Competition Kit in the S&W M&P M2.0? It makes the trigger action of that pistol just like the SA of my DA SA pistols that I have Competition tuned (I’m also a hammer fired SIG, CZ and S&W M&P Armorer). I ask because if you say the Apex kit in the P320 produces the same result as the Apex kit does in the M&P 2.0, that may very well be the ultimate trigger action I envision. I know exactly what I want and all my work is geared toward achieving it. I understand how the reduced power TBS can contribute to reducing the Trigger pull force. Since I already have one GG kit installed and another ready to install, I am going to place a Want Ad for an Apex kit that someone wants to sell, conduct different trials with it alone, conduct trials with it paired with some other parts and then compare the results obtained with all the aforementioned trials to the results obtained with the GG kit. I recorded all the detailed measurements I took as I went from stock to an installed GG Competition Kit. I will do the same constantly throughout my upcoming trials listed above. When I do action enhancement work for others, some want a complete upgrade and that’s that. Some want data as I progress through the enhancement process, and elect to stop at a certain point when I’ve achieved what they want. Some even ask me to progress, then go back a step or two when they see the numbers to get back to what they want. Again, the process is all geared to getting the pistol in the sweet spot they desire. At the end of the process, I provide their before and after measurements. Finally, as you note above, drop in parts make substantial improvements. Action tuning and careful, targeted polishing by an experienced Armorer maximizes the improvement possible, taking it the rest of the way home.

I am a Sig Armorer and personally own two P320 XFives. As part of my Action Enhancement work, I’ve done one thing to retain a crisper trigger after installing a GG Competition Kit, and I have two additional interesting tests to conduct related to this during next month or so. 1) I installed the stiffest OEM Sig trigger bar spring (TBS) I had in my inventory with all of the other components present in the GG Competition Kit. Trigger pull in this configuration is 2 lbs 7 oz. Both the break and reset are good. I say “good” because I am shooting VERY well with this configuration, but if I had my druthers, I’d like both just a little bit crisper. Note 1A: I went back to the Sig TBS because with the entire GG kit installed, including the reduced power TBS, my trigger pull was 2 lbs 1 oz and both the trigger break and reset were too soft and not distinct/crisp enough for me. Note 1B: My measured pull force is the result of measuring 10-20 pulls with my digital gauge exactly where the center of my finger is positioned on the trigger and pulling the trigger with my electronic gauge at the speed my finger moves during live fire, to the best of my ability. I do both of those during my tests because both variables significantly affect the measured pull force and I need my measurements to be as close to what they are in live fire as possible. 2) I am going to remove one or both of the lower strength GG sear springs and reinstall one or both of the OEM Sig sear springs. 3) I am going to reinstall the OEM SIG sear. It will be very interesting to see how this works out because GG states that they have changed the dimensions of their sear where it interacts with the striker to improve release and thereby improve the action of the trigger system.

Moved to “P320 X5 Trigger options?” thread.

The GG kit has a sleeve installed over the pin through the frame to reduce overtravel. It stops the rearward motion of the trigger earlier, after the sear has released the striker pin. The kit also includes reduced power trigger bar and sear springs. The kit makes a positive improvement. Apex offers a trigger bar kit without their trigger so you can retain and use the stock Sig trigger if you want or need to = Apex Kit #112-041. This kit supplies their Forward set trigger bar, overtravel stop and overtravel stop spring. They do state that the changes/improvements are different in the XSeries versus the original P320s.

My XFive is running a Grey Guns Fat Guide Rod. I bought Wolff Springs Colt 1911 Mark IV and Gold Cup Model springs. Pictured below is their 13 lb #41913. I have two more Wolff Springs, a 12 lb. #41912 and a 14 lb. #41914. They have other springs with different rates. There are others who sell them, check Springer Precision and ISMI. Springs have either round wire or flat wire. The guide rod will determine which type of spring is needed, round or flat. Also, be careful to get the springs made for a 5” long barrel.

Received my TXG Grip module assembly from the Sig Academy Pro Shop via FedEx on Tuesday. (They shipped it on Friday.) It came with the magwell & its mounting screw loose in a baggie and the BIG honking weight installed in the grip.

I have two “Standard” P320 XFives and just received my TXG grip module that I will use to replace one standard grip module. Shooting a standard XFive with the standard grip module, I agree with a perceived increase in recoil with lighter recoil spring, Jtmilne. I have a Grey Guns Fat Guide Rod and 15, 14, and 12 lb rated recoil springs along with the stock SIG recoil spring & guide rod assembly. I have not yet shot the 12 lb spring because of my experience with the stock, 15 and 14 lb springs. The sights settle back to proper position best with the 15 lb spring that came with the GG Fat Guide Rod. Going up to the stock Sig recoil spring assembly or down to the 14 lb spring makes the pistol recoil more AND the sight picture more unstable and slower to recover. - I’m shooting factory Federal 115 gr AMMO at 129 Power Factor until I can get my Dillon press set up. - My casings eject 3 feet to my right. The last one ejects differently on the empty mag. - I am going to weigh both pistols in Standard XFive form and then with the TXG grip module. - I will be shooting the heavy TXG module this weekend under both of my Standard XFive slide assemblies - one has iron sights and one has a Romeo1 on top of it.

I have had the same problem with the P-09 Kadet, I must double strike some rounds. I am considering doing what you did, filing the slot the retaining pin hits to let the pin go further forward. I will do that now. Also, the names and descriptions of the Kadet firing pond in their website are quite confusing. I also called CZ to understand exactly which is which. Finally, I can most definitely use a firing pin and spring for a CZ 75 Kadet - I am trying to get my SP-01 Shadow to run with my Kadet2 with no failures, like it does on my SP-01 and have made the original pin unusable via that development work. I will PM you. Thanks!

The voluntary upgrade does involve machining. A V notch with a rounded bottom is machined into the right rear of the underside of the slide. It mates with the new safety button/lever now installed in the sear housing.

I’ve never used the magwell because it’s not legal in SSP, so I don’t know if I’d be faster with it installed or not. My EDC does not have one so practicing and competing without one is also better for me.

The IDPA Area Coordinator for my state replied to my question. Based upon the fact that SIG is selling the P320 XFive Legion with the TXG grip module installed as a regular product in the P320 line, along with the fact that Sig is selling the TXG grip module itself, then: I would say at the equip table it would be SSP legal (minus the magwell) provided it makes weight. ESP legal with the magwell, provided it makes weight.

There has been a lot of speculation about legality of the TXG grip assembly by itself, most of which pertains to IPSC and USPSA. I am interested in IDPA’s ruling. I just spoke to the Corporate office and was given the name of our Area Coordinator and advised to route the question to him. I am doing that now and will report back.

The Plan I just ordered a complete TXG grip module from the Sig Sauer Academy Pro Shop. I have two standard XFives, one set up with iron sights and one with a Romeo1 on it. I currently shoot SSP (I have not yet tried Carry Optics) so I am going to swap the TXG grip module for the standard XFive grip module, put my original FCU in the TXG grip module and then put my standard XFive slide assembly with iron sights on top of that TXG lower assembly. I will also remove the magwell because magwells are not allowed in SSP. As long as I am under 43 ounces, I am good to go. The Question What is IDPA’s ruling on what I propose to do?

1) Lone Wolf advertises their steel extractor as tough enough to handle dropping the slide on a chambered round, whereas powdered metal/MIM extractors are brittle and doing that will cause the claw to break. They make them for other brands of pistols, also. 2) Gray Guns makes a Fat Guide Rod (big fat steel) in black and natural stainless for many different SIG pistols, both P320 and P22X Classic Series hammer fired. The P320 XFive Fat Guide Rod is made to accept 1911 recoil Springs and comes with a 15 lb recoil spring in the box (actually, it is a Ziploc bag),

You are correct. When I could not locate the TXG grip module on their website, I called them. The gentleman who answered the phone explained that SIG asked them to refrain from selling them until a future date, so they removed them from their website. He also advised checking their website periodically because they may be able to sell them in a few weeks.

@Akkid17 I am looking at their website right now. Can you point me to the exact spot on their website where I can see them at that price?? Thanks much! PS - that’s a beauty above.

Sig just announced that the TXG tungsten infused grip module is now for sale by itself for $300. https://www.sigsauer.com/store/p320-x-series-txg-grip-module-assembly.html?utm_campaign=TXG_GRIP_MODS&utm_medium=email&utm_source=Eloqua

Thank you, Bill. The data you provided, along with confirmation that several other folks are using that sight successfully, is just what I need.

What lower height front sight have you guys used successfully? Please provide both total height sight and height of the sight above the slide when installed, if possible. Also, if you have the part numbers of your front sights that allowed you to screw down your rear adjustable sight, that would bemost helpful. Note - I ask for both dimensions because I love Dawson FO sights, but I have had several sights come to me much too high when I used their standard measurement of “measure from the top of the slide to the top of the sight” method. Thanks in advance!

Neither would I have considered them. Their prices are usually stupid high.

They specify the complete striker assembly to maximize reliability. If it’s a range gun, it’d be interesting to see how many rounds the pin will go by just replacing springs. People using a P320 for EDC and Max Michel should, out of ultimate conservatism, change the whole assembly. (My EDC should obviously perform flawlessly. And, when one is going for a World Championship, we must have our pistol fire every time or that World Championship slips right through our fingers... )

This should help with your maintenance and spare parts planning. Note - I took the Armorer Class before the XFive was released, however, the FCU is the same for all P320s, to the best of my knowledge. That being understood, those of us shooting an XFive competitively should probably adhere to the recommended intervals due to the “hard” use we subject the pistol to. I completed the Sig Sauer P320 Armorer's Class in late 2015. Here are the Sig Sauer specs from the factory manual on that date. Note - the intent of this post is not to publish proprietary SIG specs, rather, to communicate information that directly affects the reliability of these pistols. That is critical when they are used as Duty & EDC firearms and important when used in Competitions. As such, If anyone from Sig is looking and has a concern with this post, I submit that they should not because following the Sig recommended maintenance intervals will make their pistols have a good reputation versus a poor one. Detailed disassembly and inspection by a trained armorer = every 3 years or 5,000 rounds. Recoil Spring for P320 full size = 10,000 rounds. Compact & Subcompact Recoil Spring = 5,000 rounds. All 320 pistols, regardless of size: • Extractor, Extractor Spring, Striker Assembly & Takedown Lever: all of those = 20,000 rounds. • Slide Catch Lever, Slide Catch Lever Spring and post = 10,000 rounds. • Magazine Spring = When the magazine fails to lock the slide open. Our instructor also uses this rule personally - when a used mag spring is permanently compressed 1.5 coil lengths shorter than a brand new mag spring (a new "master" spring kept for reference), he replaces it. Just as importantly, here are the important new things I learned about LUBRICATION: • Striker assembly is cleaned and dried only. DO NOT LUBRICATE THE (FIRING PIN) STRIKER ASSEMBLY. • Sear and sear assembly is cleaned and dried only. DO NOT LUBRICATE THE SEAR ASSEMBLY. As a mechanical engineer, the “don’t lube the sear assembly area” originally did not make sense to me. It did make sense after we disassembled the entire pistol and I saw a few things and experienced them for myself. 1. The materials that those parts are made of are innately VERY slick. 2. The parts do not move very much at all, they rock a for a short distance and that is it (they are not rotating in circles like a crankshaft). 3. Because they need no lubrication, adding lubrication simply gives carbon, dirt, etc. a place to collect and really gum up the works. 4. My personal experience = when when the action parts (sear, etc.) are lubricated, my trigger action got sluggish and very dull = not crisp on break and reset. I genuinely hope this helps you guys.
