Thanks for the info. Believe these are the exotic, read ouch when you shoot it, lightweight type aren't they? I have, unfortunately, became recoil sensitive as I have matured. Arthritis and such I guess. I don't have any of the ultralite type guns at all, just uncomfortable after putting a few cylinders downrange. I do like the new nightguard, but again, it is probably on the light side for much shooting. I have even loaded down and still feel it after a bit. I am just not as tough as I used to be!
