I just transferred from city to county. At my last agency, we carried Safariland 6360 holsters, which are my favorite duty holsters. The draw is smooth, even under high stress. My current SO uses Safariland 6280 level III holsters with the sls hood and sentry. I'm slowly adapting to the sentry, however, the inside of the holster has what appears to be a thick leather/suede liner, which makes for a pretty snug fit with my Glock 22 and TLR 1 HL. I've noticed when I draw with this holster, there isn't nearly as much forgiveness, which concerns me in a high stress environment. Often times the thick leather liner will catch on my duty weapon when I draw. The liner is textured like worn leather and is almost tacky to the touch, so it sticks to the finish of the Glock when drawing the weapon. Any advice on smoothing out/hardening the liner?
