Good guess, that’s what I’m thinking as well...however, the mark iv has a bit of an unfair advantage because I’ve put about 2500 rounds through it in the last couple months! It’s a fantastic shooter.
Side note: I just brought home the Belgium browning challenger today, and the fit, finish and overall quality of this pistol is astounding. It’s miles beyond the American made challenger ii, and, frankly, miles beyond any other 22 pistol I’ve ever held. The trigger is absolutely incredible as well. The gun is in excellent, near mint condition (but without the original grips), and I was able to get it for only $450 out the door on gunbroker! Seems like an absolute steal for this kind of quality!
Anyway, apologies for hijacking my own thread, but I’d highly recommend that y’all take a look at the Belgium Brownings if you haven’t already done so!
