initially with my hybrid i had to tighten up the crush bushings after the first 6 months or so, but havent had any issues with it since, i can still hold it upside down and lightly shake it and it holds as long as i dont get too crazy shaking it. ive bounced across cotton fields on a 4wheeler with it in the SOB and only problem was the holster came off my belt... my fault for not making sure it was all the way over the belt. usually if i know im going to be climbing up and down deer stands or on and off the 4wheeler i have an Uncle Mikes cheapo with a hammer strap i use.
