Before I stupidly sold it, I carried a 3913 in a Milt Sparks 55BN. The 55BN pulled the butt of that pistol in close and was very comfortable. Of course, it was a Milt Sparks so fit and finish were perfect. Although you'll have to wait a bit, you can't go wrong with Milt Sparks.
That was a great combo, and I regret selling it very much...
