Well, as much as I prefer shooting 40 minor over 9mm, I'm going to change. For one thing, the 3000+ 40 heads I thought I had turned out to be mostly 45s. It's not worth changing over the press for 800 40s, so I'll sell the heads and give the 2.5 gallons of once fired 40 brass to a Limited shooting friend. I just received a CZC SS 9mm barrel for my CZ 75 TS 40. I'll be fitting it shortly. I know that conversion works, because so many others have done it. Hopefully the mags will work as well. Then I'll just stick with 9mm and 45.

I must just be lucky. Every time I've checked in the last 6-7 weeks, the 124 JHPv2 have been in stock. Never the 115s.

I use AA7 and SWMP and I get nowhere near the sparks you show. Also, they are super clean. If you are getting more than just a thin film that wipes right off, change your lube. I have nothing against 3N38 except I cannot fit enough in the case to make major with a 115 JHP. I wish I could use it. It is often easier to find than AA7.

@kewi Here is some additional advice. Do your transition testing on a steel challenge range, and on the clock. Steel Challenge is ALL about transitions. SCSA is all surrender draw, but you can scoop draw for your practice. Smoke & Hope, Speed Option and Five to Go are stages with wide transitions. Load 10 rounds in each mag and have at it. Record your string times and compare. After about 20 strings with each gun, you will know which is fastest. Talk to good SCSA shooters. They will tell you a light gun transitions fast, but is harder to stop without overshooting. A heavy gun will stop on a dime, but is slower to move. You have to find the right balance. That's why I recommended you try other peoples guns. Since this is practice, do some strings as double taps. You may need more than 10 in a mag for that.

He should be warned. If it continues, DQ for unsportsman like conduct.

I hear you. Unfortunately, I cannot eject someone from the match for being a slacker or an ahole.

I don't think adding a comp and developing another load is worth the effort. Just shoot the same load you would use for LO and be done with it. If you really must have a comp, shoot your LO load through it. It will make a difference.

Unfortunately, you cannot do that at a sanctioned match.

It could happen that way. There used to be two fat sobs that shot two guns and never painted. If forced to, they would intentionally waddle downrange so slowly you wouldn't ask them again. Eventually, everyone learned their names and no one would squad with them. They got the hint after a couple of matches and stopped coming.

I really don't understand the reticence of a 5-man two-gun squad. Yes, it can present a problem. I t generally doesn't. Sometimes as an RO I'll go down range and paint the close targets. Sometimes the scoring RO does. It is an unusual situation where there is only one painter. It only happens when a shooter goes to the bathroom or has some other problem. FWIW, I just can't see going all that way to an SCSA match and only shooting one gun. If you won't let me shoot two guns. or you charge me double for the second gun, I'm gone. Around me the second gun is $5 or $10, depending on the club.

FWIW, I've found Hornady HAPs to be the most accurate JHP in all three Open guns. They are followed quite closely by the Zero clone. Next comes Everglades and Precision Delta. Differences are small. When I run out of the Zeros, I'll be using PD 115 JHP V2s for 9 major and the same in 124 for 9mm minor and subminor.

I don't have a problem with selective preferential treatment. The second club I mentioned allows the setup crew and some ROs to register the Thursday before registration opens to the general public on Sunday. I think that's fair, because they fill in 60 seconds or less. Another club I used to shoot USPSA at did something similar. They were always maxed out 30 to 60 seconds after registration opened. The wait list was a mile long. Often, they did not have enough ROs to go around. So they stopped squading until approved. They approved all the ROs and CROs the day of or the next day. We were expected to distribute ourselves evenly among the squads. The next day everyone else was approved. Worked like a charm. There were always enough ROs I only had to run four shooters before passing the timer. I wish another club I shoot at would do that. Twice last year I was the only RO on a squad of 15. It was exhausting.

Try some other peoples guns first. Transition speed and accuracy come from balance. A muzzle heavy gun feels like you are swinging a log. A muzzle light gun transitions a little more quickly, but accuracy suffers. The muzzle is so light that any imperfection of you trigger pull moves the muzzle off target. Tried all the ways you can think of. Balanced is best for me. 4.6 vs. 5": less muzzle rise with the 5.

A 3.2gr Delta is enough that I wouldn't use those bullets if you gave them to me for free. Case volume variation is something to consider. It makes a difference if you are using mixed HS brass. See attached. I copied this from a thread here, but no longer remember who posted it. For 9mm major I use once-fired, fully processed brass with the same HS. SDs range from 4 to 6. For 9mm minor, I now use mixed range pickup. I do have some problems. 9mm case capacities.pdf

I remove weight where it doesn't matter until it balances where I want it. See below. Or this. My Limited gun converted to LO. There is more slide lightening than is shown. Basically, I removed as much weight from the slide as I added with the mount and dot. The Al grips are off and it wears Lok thin G-10 grips now. Weight was removed from the frame in the rear when I reprofiled the grip and undercut the trigger guard.

20 rounds loaded. That's midway between 10 for classifiers and 29 for the big stick. I dry fire with 20 dummy rounds in a mag. For the LO pistol I will eventually build, 10 rounds.

If you want weight at the front, use a long, wide frame for your build. Use a bull barrel. I prefer a balanced gun. I want it to balance on my weak hand index finger.

If I have to drop a mag in mud, dust or snow, it gets cleaned before it is used again. I have three STI Gen 2 mags for just that purpose. Otherwise, I use my MBX mags. I shoot with an M Open shooter who cleans his mag EVERY time it gets dropped. He disassembles, runs a microfiber rag draped around a mag brush through it, then sprays it with Magslick before reassembling. I just run a brush through mine.

The club I shoot SCSA every month used to have 5 squads and it filled on Practiscore. Generally, you could still get in, because they allowed 60 shooters. Then they went to 6 squads. This year they went to two days, Sat and Sun. The MD wanted to shoot four guns. Almost no one shoots more than two guns. More shooters registered. Now there are always 90+ guns at the match.

I don't know about that. I often shoot on squads with 5 or 6 2-gun shooters and never have a problem. We are always finished the stage before a larger 1-gun shooter squad is done. In last months match, our squad of 5 two-gun shooters and one one-gun shooter finished 45 minutes before the last squad finished. We had everything stowed, and were waiting to help out with the other stages. Now this is at a club that specializes in SCSA matches. EVERYONE knows the drill. Another club that only runs three SCSA matches a year, a whole different story. At the last match there, we finished, spent 20 minutes talking and decided to stow the stage. After another 15 minutes the MD came around and asked were the targets were. OOOPS. We reset the stage in under 10 minutes and squad six still hadn't shown up.

By a long shot. If the Glock EOM 33-round mags with extensions had worked in my PCC, I'd still have them. No clue why. I clean mine once a year. Six 17-rounders and three 40-rounders. They do get dropped, but not often.

The problem is the mag catch on Glock and several other mags. The catch is only a depression, not cut through as on MBX Glock mags. The additional weight of the metal extension and the extra 10 rounds is too much for your mag catch. You insert the mag, load and fire. The extra weight and the recoil jostles the mag enough the next round won't feed. If you hold the mag in, it will feed. After you do this for 3-4 rounds, the mag is light enough to be retained in position by your mag catch. You cannot solve this problem if using Glock 33-round mags as your base. SMS mags won't work either. Don't know about ETS 33-round mags. I had exactly the same problem on my PCC. I sold the mags and extensions and bought 40-round ETS mags. They work 100%.

Examine the 10" barrel breech end, chamber and chamfer and compare it to whatever 16" you still have. What is the difference? That's where you will find your answer.

I'm a B Open shooter in SCSA. Before I built real Open guns I used a LO gun in Open. Some of the fastest times I ever shot were with that gun. I was a lot younger and faster then. Now I shoot my backup 2011 Open gun for SCSA. The Open load is 124 JHP @ 155 PF. I also shoot my minor regular load through it. 124 plated @ 132 PF. The Open load is definitely flatter.

For those of you enamored of Clays but can't find any, Alliant Clay Dot is a direct replacement. Even Hodgdon's Ballisticians admit they did a great job reverse engineering Clays.
