I have a pair of OMM's one in .22 and one in .38 The .38 was popular with NRA type shooters in it's day, and I gather was considered a bit better than the K38 by some, but they were not as popular (price?) The OMM seem to have a very nice single action, but a fairly heavy double action NRA shooters did every thing single action, so it may not have mattered much. I will probably leave these guns alone and not have anyone mess with them as good Colt mechanics are thin on the ground. On another tack does the OMM have the 1 in 14 twist of the Python?

Welcome, K38! Although, your monicker tastes like a Capulet in the house of Montague! We must have talked with the same people and read the same books - I think you're right about the OMM and SA target shooting. I've always wanted to have a set of a 22 and 38 Colt - but haven't got 'em yet. To my experience, also, Brand X always outsells Colt and my feeling is pure price. You've met dfariswheel - he's our voice of authority, that's for sure. Don't know about the twist in the guns - but I'd LIKE to, too!
