Peter, did you ever see a L.A.R. Grizzly? Available in 44 Magnum revo ctg. Tons of fun, well made, exciting, like a big ol burly premium quality 1911 with a terrific trigger. Costs oh a grand or so. Excellent bang for the buck. JMHO
BTW, ditto what Sean said re: ballistics. A 9mm is a 9mm is a 9mm. Whether Luger, Super, 9X23, 38 Casull, the performance will not provide the punch of a larger, heavier caliber. Too small, light a pill. The 10mm will actually be a stronger performing round than the 38 Casull when properly stoked.
