I recently received an accessory for my GP-100 MC in 10mm.
It's an extended cylinder release for competition. It looks a little funny,, but it sure works VERY, VERY well. My speed reloads seemed quicker & smoother today at my local USPSA match. And it must have worked because my scores reflected a "good day" at the match.
Hogue makes the cylinder release lever,, and I LIKE it.
Now,, I know some folks have no need for such a device,, and that's fine. But I wanted to give a review of it for those who MIGHT like one.
