I once had a BUL M5 Government. Daly is just the importer, the pistol is Israeli and is widely used in competition abroad.
Shot OK, actually felt better than any .45acp double stack I've known (USP, Para, SA Hi-Cap, G21). M-5 GM mags aren't any more expensive than Para or USP. Shop around.
Most of the go fast parts have to come from abroad so aftermarket sucks. Tight chamber kept jamming snapcaps, although it functioned flawlessly with live ammo. I wish they hadn't used a bull barrel, but the slide is slotted for a regular 1911-style bushing. Not bad if the price is right.
Your short barrel version maybe exhibit the same 1911 short barrel probs of the past.
