It's Spears for me. Darrell Johnson is the owner. Shops number in Kansas is 620-200-3220
I used a Hobblit for my Super-X, a Allor for my K-80 trap special, a Precision Gold for my Perazzi TMX, I've used only Spears for my Model 12's and also Spears for my Berettas, Remington 1100 28 gauge, and my Browning Citori.
I have used Allem's for two guns, I had to much trouble with them. Asked for no refund, just removed all their parts and replaced them. All was good again. I'm sure they have improved with there roller release.
Have no idea where lgshot got Kevin as the contact.
