A lot of folks shooting suppressors find that their guns don't run right at first. The problem, apparently, is that the factory recoil spring assemblies are too stout when running the suppressor, as the suppressor affects how the slide recoils. Getting a lighter RSA, if that's possible, or leaving the slide locked back for a week or so typically solves the problem.
Note: Coil springs kept compressed at or near their elastic limits will slowly degrade. If the springs don't compress deeply, the degradation is much, much slower. Whether the spring is routinely deeply compressed is a quirk of a given gun design, etc. Some magazine springs and some recoil springs aren't pushed that far when running the gun in pure stock form. But all coil springs will take a minor set when
first installed, and it may just be that using a suppressor slows that process.
If you try locking back the slide to speed up the process, the secret is to not do it for too long. The guys on the FN Forum have found that locking back the slide on their FNX guns for about a week (give or take a couple of days) makes a subtle but significant difference in whether the guns runs with a suppressor mounted.
- That's probably because, with a suppressor mounted the spring isn't fully cycling at first, and it probably takes those extra 200 rounds to get just enough extra wear for the gun to function properly with the suppressor mounted.
Wolff Springs offers non-captured recoil springs and stand-alone guide rods for various Glocks, and I wonder if any of those assemblies can be adapted for use with the P10 series of guns? If so, you can just use a different spring when running a suppressor. I have several Glocks and FNS pistols, and a P10C. I know that the stand-alone Glock recoil springs and guide rods are almost identical to the FNS models of comparable sizes. (Glock uses the same guide rod assemblies for the Glock 17/22/37 and does the same for the the 19/23/38.
- The standard FACTORY (captured) RSA of the P10c is just a bit longer than the Glock 19/23/38 RSA. The Glock replacement for the RSA probably wouldn't work in the P10c
- The Glock 17/22/37 recoil spring assembly is a hair longer than the P10C recoil spring, but if you run a Wolff Guide Rod and Spring, that small difference would stick out the front of the slide and would not have any effect on function. That said, I just don't know whether the diameter of the Wolff guide rod will work in the P10c slide. (I wonder if other CZ guide rods are compatible?)
Since I don't run suppressors, and am not having recoil-spring problems, I'll probably NOT ever buy a Wolff guide rod to find out.
