P250, P320, P320 X-5, M17, & M18 Pistols
I plan to do a lot of dry fire drills with my P320CA .357 SIG.
Are snap caps recommended for dry fire drills with a P320?
If so, the only snap caps I can find are the aluminum A-zoom -- which I've heard can leave aluminum shards in my chamber. Are there any brass center snap caps out there...
