I don't mean to be rude, but there are better things to spend your money on.
Ammo comes first to my mind.
The barrel is threaded for a suppressor, not a muzzle brake.
Somebody saw those threads and said, Ummm?
I think I'll make some money?
The 45ACP does not recoil enough to require any type of muzzle brake.
Especially a big pistol like the USP Tactical. If recoil is a problem,
switch to the 9mm?
A muzzle brake may be necessary on large caliber rifles or on full
auto weapons, but not on a semi-auto 45 ACP pistol.
It's a waste of money. That's just my opinion.
I don't care for 90% of the "gadgets" on the market today.
