I keep all my guns " very clean "
It's a semi so yea you have to keep them clean and ajusted well or they can jam. I have talked to a few people that have had them and they liked them alot. It's really just a Home Defence gun and will only get a few rounds though it a year just to keep it in good working order. Theres no way I could aford a .45 as a full time target gun.
