@Jeff O my Stock III had a polygonally-rifled barrel that was as straight as can be. Either something changed, or the website is off.

Then, sweet. Curiosity satisfied.

Like a Stock 3. But not a bull cone-fit barrel, like the Limited and the Stock 2?

A Stock 3 does not have a cone barrel. It’s a straight-walled barrel.

@Les Snyder just sent me a PM thanking me for suggesting the BCM extractor spring. I tried multiple things before my gun finally ran 110% reliably for 1,000rds without a fault. The extra power extractor spring was the change than finally fixed the gun. Les just went to the range, and has found the same thing. His gun is running again. To answer your question, I’m running a KE Arms Ambi glock-mag lower with a factory CMMG Guard upper.

I’d like to add a sub-set to this which helped me. Hold the gun in the position you’ve decided to use when reloading. However high you like, with magwell pointed at incoming magazine. (Your gun needs to be positioned so that your offhand is pointing the mag into the gun STRAIGHT by the way. Mag tube and forearm in a staight line... no bend in the wrist when you arrive at the *properly aligned* magwell!) I suggest finding the sweet spot and holding the gun there, rotated and ready. Grip the mag properly, draw it, turn your arm over and feed it straight into the gun, inserting halfway. Pull it back out, put it in your pouch, and repeat. Isolate the portion that’s hurting you. Do that 25% of the entire reload. Then perform the whole thing. There’s no reason you should be using a timer until you can perform the drill correctly. Turn the par time off until you can do it 100% correct in 8 seconds. Then turn it on and try for 7, then 6, etc.

The most important thing to look at is consistent presentation: 1. Are you gripping the magazine correctly every single time? 2. Is your gun in the exact same place every single time? Both of these vary a little bit for most novices.

Putty would add too much thickness. Original slow-cure JB weld, the stuff that is dark gray in color when mixed... and gives you a whole lot of working time. Don’t use a 5 or 30 minute epoxy.

I assume this took place in Production or CO? If so it’s never permissable to start with the gun in single action. Unless you’d like to finish the match in Open - or a match DQ if you don’t activate the safety.

@PeterParfinik are you by any chance coming from more of a precision rifle background? Many of us USPSA types clean things every few thousand rounds (or every few months of regular use) whether they need it or not. Does it shoot straight? Does it run 100%? Run a boresnake through it, oil it, and call it good.

@waktasz I have only shot two matches with them, lately I switched back to production for some time with good old irons. While they proved reliable, I don’t have a large enough sample to say that they’re bombproof by any means. Particularly because there is such a huge variable present in how each one is fit to the magazine tube.

SSP A holster. Two magazine pouches on your belt. 10 rounds in those mags for reloads. 11 rounds in a third magazine in your front pocket. Load this one to begin each stage. (unless it’s an unloaded start. Then all of your mags are loaded to exactly 10 rounds.)

Based on my experience with a Walther: The gun is already well-balanced, and it’s current balance is what you’re used to. In light of that: 1) Try to have the weight loss done so that it balances roughly how it does now - including the weight added by the optic you choose. Don’t take *all*the weight off the front then add a 1.9oz SRO or DPP in the back. 2) Keep the total weight loss down to around 0.5-1.0oz or it will make the recoil noticeably more snappy. That means that if you pick a 1.5oz optic, don’t take more than 2.0-2.5oz out of the slide. Most handgun slides are in the neighborhood of 12oz, plus or minus an ounce or two. That means that a 0.5oz weight reduction is definitely noticeable.

This is not a statement you’ll continue to say online the first time one of your mags is picked up off the ground to discover a broken feed lip. Especially likely if it’s cold.

This is where I’d go. Baseball players regularly do their thing on hard-packed dirt, other sports don’t. Change shoes if there’s a little bit of rain, and you don’t want to sprain seven ankles during the match by ice skating across wooden fault lines.

I’m not saying a rope ladder and pole vault, or even a 30meter sprint, should be commonplace. Not MGM Ironman stuff... I just find it disgusting that we Americans have gotten so weak and lazy. Someone saying it might be too challenging to pick their feet up and step into a tractor tire should immediately have people laughing harshly in their face. Cooper tunnels, low ports, balance beams, and 40 feet of movement during a stage or two are great additions to a match. Yet they’re frowned upon because they’re (whatever)? Lame.

For approximately the first thirty years of it’s existence. Think about the real implications of the word “Practical” when it comes to shooting. Practical... for what? Nowdays we’ve turned it into a sport. I actively hate the idea of watering it down so throughly that a guy with two bad knees and a beer-keg gut can keep up with a guy who trains for it both on the range *and* in the gym. And I’m not lucky enough to posses two healthy knees, so I’m not saying that because I’m a 20 year old sprinter. You shouldn’t need to be Usain Bolt to finish well, but it damn well should challenge the hell out of some fat guy who can’t manage three pull ups in a row or climb in and out of a frickin’ tire... Or this is gonna get boring.

Or you could chose the gun on factors that make sense, and adjust to the gun with a few hours of consistent dryfire. That’s like picking a car based on which one has the best feeling seat.

Things have changed over the years. Shooters have gotten faster and better. Techniques have undergone two decades of refinement and experimentation since Brian was active. Guys like Vogel and @CHA-LEE are out there gripping the gun tight as hell, and nowdays GMs are shooting faster and more accurately than anyone has in history.

The side view probably isn’t wide enough to make certain state legislations which mandate LCI’s on new firearms happy. (CA and MA are likely why everyone is making guns with this feature now. It’s easier to put this feature on all the guns you sell.)

@Les Snyder you have to pick a magazine brand when doing this. I run only Glock OEM mags... attempting to run ETS mags would result in some fractured feed lips. The metal glock lips are thinner and give you more space for the teeth of the bolt to pass between them with the mag up higher.

Just the bare spring, yes. It’s heavy enough to be a PITA to install by itself, and getting anything else in there was proving to be impossibly tight.

@Yagi the Stock 3 has a bull barrel. The Stock 2 has a cone-fit (bull) barrel. The Stock 2’s lockup system is superior to everything else when it comes to accuracy, including the vaunted Accu bushings in the CZ. Along with a preference for less weight out front, that’s why you see a dozen Stock 2’s for every Stock 3 at matches. (This all comes down to hair splitting. I ran a Stock 3, liked it’s balance, and all three guns described above are all hideously accurate. More than enough to perform well in USPSA.)

Why on earth didn’t they build it with a cone-fit barrel? That one feature is the primary reason everyone chose the S2 over the S3 when it came time to choose a Tanfo. It’s why the old model outsells the new one currently, so you’d think that would be the first thing to tweak when building this Stock 4 into the Uber-Tanfo.

I suspect a single port comp or 9mm sight block barrel are for guys shooting it recreationally, or in 3-gun / steel challenge with Minor ammo.
