MKitzmiller Posted June 24, 2016 Author Share Posted June 24, 2016 I'll dig into this in a few hours and do some chamber checks. Spent the evening researching torque specs for the optic mount as it damn near fell off after 50 rounds yesterday. Link to comment Share on other sites More sharing options...
tyler2you Posted June 24, 2016 Share Posted June 24, 2016 Welcome to Open If you haven't had issues with mounts coming loose, C-Mores losing zero, baffle strikes on the comp, ejection problems, rackers falling off/hitting your thumb, or comps coming loose, you haven't been shooting Open long enough. I gave up on the little 5-40 screws that were originally on my RTS2 mount. Even with Red Loctite, it seemed like I was frequently having one or two get loose. The allen slots on those tiny screws were also incredibly easy to damage if you put any kind of torque on them. I had the holes in my frame tapped for 6-40 screws which have worked out great. They can be difficult to find, but I bought a bag of a hundred stainless 6-40 X 3/4" socket head screws on ebay and just cut them down to length.

MKitzmiller Posted June 24, 2016 Author Share Posted June 24, 2016 HA!! That's the most awesome welcome ever! I've been shooting open long enough to know that plastic C-More slide rides require way too much re-zeroing,(hence the RTS2 on this gun, the ejector on my STI has been replaced twice, and I Loctite the comps as soon as I get a gun.. I ran blue Loctite and 18"lbs on it last night.. We'll see. If they come loose one more time, I'll re-tap. There seems to be a pretty decent amount of meat on the frame compared to my STI's..

These aren't issues I'm unequipped to handle. Never bought a 4K pistol that needed immediate attention. She'll be runnin like a top in no time. You in LaPlace eh Scooter?

tyler2you Posted June 24, 2016 Share Posted June 24, 2016 Red Loctite on the frame mount screws, blue on the optic to mount screws has worked best for me. One more tip that someone gave me along the way--use green Loctite (620) on the comp. I struggled for quite a while with my comp loosening up and causing strikes until I switched to the 620. I tried red 271 and green 603, but after a long practice session, they both allowed the comp to shift. The 620 is designed to bridge larger gaps like between the threads and it's resistant to high temps. Link to comment Share on other sites More sharing options...

These aren't issues I'm unequipped to handle. Never bought a 4K pistol that needed immediate attention. She'll be runnin like a top in no time. It happens. I'm struggling with a full custom open gun right now. Often times builders don't loctite some screws because you might want to change something around etc. I red loctite the mounting screws into the frame. When done properly they don't have to be torqued, just snugged up tight. The key is degreasing 100% for the loctite to work. Link to comment Share on other sites More sharing options...

You may still want to see about having Matt throat your barrel so you can use a longer OAL. It gives you a bit more margin of safety with 9 Major and allows you more freedom with bullet profiles if you decide to change up at some point.

tyler2you Posted June 25, 2016 Share Posted June 25, 2016 You might get lucky. I put my barrel in the mail with a dummy round on a Saturday and had it back the following Friday. Sent from my SM-G925V using Tapatalk Link to comment Share on other sites More sharing options...

fishsticks Posted June 25, 2016 Share Posted June 25, 2016 Why the dummy?? To be sure that the load you want to use fits after reaming. Otherwise the gunsmith is working blind. Link to comment Share on other sites More sharing options...

Check, check, check Racker hit my front tooth so hard I thought It was knocked out Finally went with aluminum cmore after 2 plastic ones wouldn't hold zero Mount loosens up every few matches, usually just the rear-most screw...even with blue loctitie No ejection issues, or comp problems...knock on wood To the OP...I run 115 gr JHP in my CK....with 7.7 Autocomp at 1.165. That round was too long for one of my STI mags with the spacer as they kept hanging up. I have since accumulated a couple old style SVI and bought a couple MBX mags. I no longer have mag feeding issues. Link to comment Share on other sites More sharing options...

theWacoKid Posted July 6, 2016 Share Posted July 6, 2016 (edited) Ran my gun @ 6.8, 6.9, and 7.0 of WAC @ 1.163-1.165. ALL too long. Anyone else running a CK open have that issue?JHP's? Yes, I had this issue with my CK and it was recently discussed here and I wasn't the only one. Wouldn't handle a 124 jhp at longer than about 1.135". Would plunk 124 cmj's all the way out to 1.185". My solution was to buy a reamer and ream the throat until it plunked jhp's at 1.175".http://www.brianenos.com/forums/index.php?showtopic=230346&hl= Edited July 6, 2016 by theWacoKid Link to comment Share on other sites More sharing options...

MKitzmiller Posted July 27, 2016 Author Share Posted July 27, 2016 That's about where I've settled. I had an OAL restriction of 1.135-ish. Thought it was my barrel needing throated. Turned out that the decap/resize die on my 550 wasn't bottomed out. Now alls good. Thanks for the data!! Link to comment Share on other sites More sharing options...
