Ok so I didn't except to have a movie quite gun but I was expecting the reverse of what happened yesterday. Took my MP-1522 and my sig mosquito out to test drive the new can. The pistol was amazing I could hear the hit on the pop can and the slide cycling forth and back. I used standard 22LR not subsonic on both guns. The MP1522 was still loud enough to need ear plugs. Anyone know why the pistol would have a lower sound out-put compared to the rifle? Thanks.
