All,
I just built my first CCRF Glock with a G17 aluminum frame. Have not had a chance to shoot it yet (tomorrow), but will post if I encounter any problems.
Except for the frame, everything else is a stock Glock. I am not a competitor, military, LE or other armed professional, just a regular civilian gun enthusiast.
I have owned and shot a number of different pistols, including aluminum framed Sig P226 in .40 and CZ P01 in 9mm (not the same thing, I know, but a good reference point for alloy frames). P01, for example, which is based on CZ 75 - one of the most reliable LE and military gun platforms in the world, does require 300-500 rounds shot through it before malfunctions stop. And we all know about 1911s, regardless of the brand. I understand that stock Glocks are expected to operate 100% reliably out of the box, but it seems that most of complaints with CCRF frames come from people who modify their guns for competition etc..
I did talk to a couple of people (firearms professionals), who have had experience with CCRF frames, and neither tried to talk me out of getting one (they would have if they had experienced or were aware of any problems).
Hope not to offend anybody, but I am not surprised, however, to hear of problems with the guns modified for competition or otherwise. CCRF specifically explains on their web site that the frames are designed for stock parts only.
Another thought – perhaps we should hear from Robar Extreme pistol owners since the company uses the CCRF frames.
