I've been carrying with a cheapo Uncle Mikes IWB holster for now until i can decide which way i want to go...but no more! I cant stand it any longer. The thing is uncomfortable, digs into my hip, and bruises which makes everything worse. Although it does conceal fairly well...not great but concealed nonetheless. Here's my problem...i cant decide whether to go IWB or OWB, and even which holster to go with either way. I have had several recommendations for Milt Sparks and Comptac. I was looking at maybe the MTAC for IWB...or the Sparks 55BN for OWB. Thing is, i will need to carry a Glock 22 at times, and at others a 27...so using the same holster for both would be a plus. I realize both would fit a holster made for the 22, but i need to be able to conceal the 22 with whichever holster i go with. I am also slightly concerned with the comfort of an IWB holster. I'm sure that not all are as uncomfortable as the Uncle Mikes, but are any of them really comfortable at all? I need any info and recommendations you guys can throw at me, i plan to order something this weekend.
