Love my Sparks. I can't add anything to what has already been said.
If you want a quality custom holster without the wait of a Sparks, Rosen, etc, try El Paso Saddlery. They've been around since 1889, I think that is correct. I believe the wait time is roughly 6-8 weeks. Reasonable prices. I like my "Double Agent."
But I am like a green olive tree in the house of God: I trust in the mercy of God for ever and ever. Psalm 52:8
