I fire mine two or three times a week, about 2 or 3 hundred rounds at a time, assorted Rem, Winchester, etc bulk packs. It invariably needs to be cleaned before 100 rounds or it gets dirty and starts to stovepipe frequently. Before getting dirty it never misses a beat. I just keep an acid brush and some solvent next to my shooting spot and give it a swab. I'll say more after a couple thousand rounds though. I too got it as opposed to getting a conversion kit for a 1911.
