Sounds like you don’t know for sure. Anyone else?

Serious question. Can’t the locking block be replaced in like 2 seconds so you can have spares with you and maybe just prophylactically replace them at a frequent interval?

Yes I don’t really know why and haven’t taken the time/don’t care enough to investigate, but was hoping someone would chime in who might have observed the same thing. I don’t think it is the grips that are the issue, I have the same grips on two guns, one works, one doesn’t. The guns that don’t work have Cheely extra wide frames and infinity triggers. Maybe one of those is the reason. Otherwise, it’s back to spending a bunch of time loading dummy rounds. Oh well.

Yes. It sounds like you’re going to have a lot of trouble figuring this out because it seems like you have a lot of trouble accepting advice. You took the mags out of spec for some reason. You get a load recommendation from Limcat but decide to go longer anyway. You hear advice from multiple people here but immediately dismiss it and instead continue to blame the mags (which are no longer in spec, by the way). Making them narrower and reliable also isn’t as easy as just “banging on the feed lips”. Good luck to you. Like Charlie said, this isn’t a Glock shooting factory ammo.

@CHA-LEE is very smart and knows infinitely more about this than I do. I would imagine that the OAL recommendations from MBX relate more to how the rounds behave in the mag, not necessarily how it feeds into each individual gun? Therefore, especially if this is a new gun, I think I’d rather have my rounds in MBX spec to work inside these mags and if they don’t, have the gunsmith start changing the gun? Or use different mags that can accommodate a different OAL without having problems inside the mags themselves?

I imagine this is for 9mm. So, in the FAQ page, recommendation for the feed lips is .340 to .350. So, you “widened” them from in spec to out of spec. Making them narrow again is generally trickier than making them wider. You can also check the outside and inside diameter of the mags on the top and bottom compared to known mags that work well. As has already been mentioned, you need to replace the spring about once every 2-3 months depending on usage, and should be cleaning the inside of the mag with a brush and a mop every single time they hit the ground. If they aren’t working out of the box, you may consider changing the spring now because you don’t necessarily know how old the spring in those mags are. And even new springs aren’t always perfect every time. Also, check your follower for burrs and imperfections that may need a little cleanup with a hobby knife or small wire cutters. Another option for people looking here with old mags is to send them back in to MBX for the mag refresh service, and get them back into spec with new guts if you don’t want to mess with them and ruin them by pounding them with a hammer yourself. Ammo OAL should be OK. I run 1.160 +\- 0.005. Didn’t mention case gauge or plunk test either. Hopefully you’re doing that as well. I have about 24 mags between 3 guns, all feed lips within these specs and all guns run 100%. I know people who run and even prefer running even longer like 1.175 or 1.18. So... it may be something with your gun itself. But now the mags are out of spec, so it’s going to be tough to chase some of these things. You may consider just starting over, get new MBX mags and not mess with them, and get your gunsmith to make them run properly with mags that are in spec. That way, when you need more mags in the future, you can just open the package and they run, rather than going through this rigmarole every time.

It might be ammo related. Is your ammo in spec in terms of OAL?

Update. I have 2 new Open guns with Cheely Extra Wide frames, Cheely grips, and the 2011 dry fire mags don’t seat or drop free. They work fine in my backup open gun which is an STI frame with a Cheely grip. I guess my advice is to try one before you buy like 8 of them.

4K? I’d buy 2 shadow 2s with optics and get back to actually shooting.

MBX and Tooth and Nail Armory have been making upward only comps for a couple of years now. Ask someone with one of those what they think. Also ask yourself, do you see any one comp design dominating the field?

There are screws in the holder, but I believe the timer slides in and out with some difficulty. I have one, I like it.

Any new negative feedback at all other than dropping the gun out in dry fire once?

Is there anyone who never cleans the barrel in their open gun? No boresnake, no brush, no patches, no nothin’?

Cool! Did you embed any tungsten in that epoxy?

Is it digging in the leg at all? Especially when comparing to Alpha X holster?

Like most things at the upper end of performance, there is a little more to gain for a lot more money. It’s worth it to some people, not to others. I have them, and I love them.

JJ just did that with a Beretta though, Oh snap. Just kidding.

Anywhere, also please specify “Plain” PVD or DLC/DLA. Thanks!

Curious to see what peoples’ experiences are. How long until you saw some wear or bare metal on your PVD and or DLC coated open slide?

Wow, dude! That’s so awesome! What a great group of friends.

I mean, it’s not a Honcho or anything, but...

Amg labs.

I bought 3 guns and they are all on time.

I’m using a Cheely E2 with the Brass magwell. They fit and seat fine. Almost a little too fine. They go in way easier than an MBX mag loaded to 23. You can cheat a little on how hard you have to seat the mag. They eject, jump out of the gun just fine. I didn’t have to dremmel anything. I can rack the slide with the mag in place. It weighs 10.2 oz, where an MBX 140 loaded with 23 rounds of 9mm weighs 13.7 oz. The finish on them is a little slippery compared to a regular mag. After a few sessions with a little pro grip on the hands, they got less slippery. The advantage in my eyes is that you don’t have to spend the time loading and unloading mags with dummy rounds and sometimes a rack buddy. They are also a lot cheaper than a real mag. Also, you are probably going to get less trouble from ROs, etc if you practice reloads at the safe table with bright purple mags, if you like to do those kinds of things.
