Rowe 75:
I use one of these for range use with my 75b. I like it, good fit a construction. I removed the spring from mine for personal preference. I can lock it in or keep it unlocked for a faster draw... Should probably put the spring back in and better my skills with the retention button.
Some local competition venues won't allow the trigger finger release holsters at all.
I was at a match where a shooter shot himself in the leg with a Serpa. Luckily, he had the .22 conversion slide on his 40 cal pistol. They left the buillet in rather can cause more damage to his thigh.
While in practice the release does position your finger well, in the "adrenilin of the moment" it may NOT on a fast draw-and-shoot situation..
Isopropyl:
Do those of you using the Bladetech find that your finish is wearing on the slide or frame of the firearm from the holster?
I have two. The DOH for a 75B took a long while to show much wear.
The new one for my 75 Shadow( Around 6K rounds of practice and comp)., shows more finish wear in 6 months than my B did in 30K rounds.
I do like the holster for function though.
