Trevor discusses why our pistols (and really all mechanical devices) require a break-in period. With the current ammo situation, it seems that the idea of a break-in period has been getting more and more controversial. We wanted to take a moment to address why we require a break-in period, and why it is important in the long run for the function of your pistol.
Technical Tuesday: The Why Behind a Break-In Period

Is the MR920L compatible with extended slide locks ?
Hi, They are compatible, but the extended ones tend to activate when not intended, so our team does not recommend them.
He speaks the Truth. I mounted a 509t on a brand new MR920 and took it to the range today to break it in. The first round took 4 tries to go to battery and I had maybe 4 more failures to go to battery over the first 50 rounds (115 grain range fodder). After that, ran like a sewing machine and it certainly likes 124 grain Gold Dot.
I have a dr920 I like it. Can this company do the same with a czp10f?
Youu have improved the GLOCK 19!Are there any future plans to improve my favorite GLOCK…the GLOCK 30S!
Just did some break in today with my son on the XR 920 some good stuff. Will continue to do the deeds. Thanks!
