It's a custom 2011. I wouldn't attempt major in my glocks.

Thanks guys, I think I'm just going to bump my loads up slowly and see what happens.

Try D2 Customs from Punxsutawney, Pa. He's a few hours south of you I think. He did an awesome job building my 2011. No website but he does have a Facebook page.

I've heard of guys doing this because the metal is stronger and it takes more pressure to flatten. I don't really what to hide my pressure issue under a stronger primer jacket. Is there other advantages of using small rifle primers?

Cool thanks for the info

They are in between but closer to the one on the left. They are starting to flatten but aren't blown through yet like the one one the right.

Thank you everyone, I'm going to try to bump up my loads a little. I'll try and get some pics uploaded to show what I believe is my primers flattening.

When I drop a round in the barrel it falls in the entire way and doesn't stick out. So in guessing that it isn't hitting the lands. Is there other ways of checking this?

I'm trying to load 9mm major for my open gun with a 3 port egw comp. but I'm afraid of over pressuring. Currently tring... 7gr hs6 124gr plated rn Winchester primer 1.170 oal Chrono @ an avaverage of 1190fps 147pf This load seem to start flattening the primers some I'm nervous to go any higher. Is this normal? Can someone help me out with a load?

Thanks again everyone my gun is a 2011 and I'm currently running a 7lb spring. I guess it's time to start playing around with some different loads.

Thanks everyone for the input. I think I might try some major loads and try to get the comp working a little better. I started with minor loads for fear of over pressuring the gun and hurting it because there's not to much info in reloading data (that ive found)for loads in major pf

Superdude, great article very helpful thanks

I'm new to open guns and was wondering how you guys get them to shoot so flat. I have put together a double stack 5" 9mm with a 3 port egw comp And mainly all Wilson internals on a ck frame. I'm trying to stay in minor so I'm currently shooting 5.8gr of auto comp with 124gr plated round nose with oal of 1.150. This is somewhat tame but still getting muzzle flip. Any advice would be helpful. Thanks
