Something tells me that Jerry Miculek could rapid fire a worked over smith&wesson faster than he could a mateba. But the lowered barrel of the mateba could definitely be an asset.
Is your’s chambered for 45ACP and full moon clips?
My Mateba is chambered for .357 Mag and the other calibers it was chambered for are 44. Mag and .454 Casull. I have never seen a listing for a Casull for sale.
After checking, any redesign for .45 caliber moonclips is out of the question. There just isn’t enough room at the rear of the cylinder.
