I bought a combatmaster from Wade's gunshop a couple of years ago, so that is great news that thier gunsmith can work on these pistols. I have a problem with the slide not locking open after the last shot, but it could be the after market mags.
Was the StormLake barrel that was installed countersunk on the crown? I have had combatmasters with both styles but it seems that the later barrels have all been countersunk. It looks impressive from the business end of the barrel!
