I just ordered a serpa holster for my new to me dominion arms 45 acp clone, according to Blackhawk model chart it should fit colt reg size and commander and all clones, well its not, my pistol is a commander size and it will not lock in the holster at all, too bad the holster look very well build, and I like the extra security to secure the pistol, just letting you gunsnutter know so you don't make the same mistake as I did.
