There is nothing wrong with the uncle mikes pocket holster. I pocket carry almost every day. I usually get over 5 years of wear from a holster. The holster you have is far to small for an LCR. I use a size 03 holster for an LCP size pistol. You can't blame the brand when you buy the wrong holster. There is a reason the size 0 holster was so cheap. It is designed for NAA revolver sized gun. Many people don't use a holster for a NAA revolver because a pocket clip is easy to install and use. I carry revolvers in a holster to keep lint and other debris out of the gun.
A pocket holster should be roomy. The holster should cover the trigger guard and have enough room to stick a spare magazine in the holster. It's not that I carry a spare magazine in my holster, that is just a rule of thumb to make sure the holster is large enough.
