It depends. On Gen3 or older guns, that is correct. On Gen 4 and newer, things can be different.The recoil springs on Glock 9mms and .40s are the same (between equivalent-sized guns).
Thanks for that correction. I completely forgot about post-Gen 3 Glocks. I don’t shoot my Gen 4 anywhere near as much as my Gen 3, so I’ve never replaced the recoil spring on it.It depends. On Gen3 or older guns, that is correct. On Gen 4 and newer, things can be different.
A Gen 4 Glock 22 uses a different recoil spring than a Gen 4 Glock 17, for example.
I'd advise against it.I had a Gen 3 31 with a LWD 40-9 conversion barrel in it, and using 17 mags, other than the reload thing, never had any issues with reliability. I wouldnt have had an issue using it outside of practice.
Unless a person understands the possible failure modes that could result and the number of rounds that each failure mode could take to develop as a result of using each of the improper parts, I think that this is an unwise approach. More to the point, I just don't see what the benefit is.I think you need to make the decision based on the performance of your gun...
This. The .40 mags are not the best choice when shooting 9mm. They may work at times, but after I saw how 9mm looked in a .40 mag, I quickly decided to buy some 9mm mags.Are you using 9mm mags?
