jic one brand you ought to ck out is Simply Rugged out of Az they make some very nice practical holsters. Now holsters for the Ruger SP101 will fit your LCRX-3 just fine and vise verse I have both LCRX & a Ruger SP101 have a Galco LCR holster that my SP101 fits just fine except my SP101 is a 3 inch and my LCRX is the snub version. Plus my SP101 holsters fit my LCRX just fine. Simply Rugged makes a holster that's dual designed both IWB or OWB might want to look at that one. I am still debating about getting a Simply Rugged OWB for my Ruger SP101. Hope you find a holster that works good luck!!!
