Picking a holster, especially for everyday use, is a personal decision that involves juggling many hard to quantify and subjective criteria. Thus we are blessed to have such a bewildering selection of manufacturers and models available to us.
If you draw any lesson from these reviews, I hope it is that there are far better, safer, and similarly inexpensive alternatives to the Blackhawk SERPA if you require an OWB kydex retention holster. I would be satisfied with any of these holsters as an alternative, and would be comfortable recommending any of them for you to check out. Caveat: you should not commit to any one design until you have wrung it out at the range and should be fully prepared to ditch it for another model if it doesn’t work out for you in any way.
If I had to rank the holsters I had a look at, I would place the Uncle Mike’s Reflex IRT last. It was the least comfortable and stable, even if the price was right and the retention system was unique and slick.
Next worst I’d say the 5-11 Thumb Drive. I felt getting the gun unlocked and out of the holster was too prone to fumbling to justify it’s relatively high price. However it was constructed very well, had very secure retention and had the widest range of adjustments, so it’s still worth a look.
I would rank the Galco M6x as second best. It did everything pretty well and was reasonably priced. But ultimately I think the Safariland 6378 is a better overall design and value and just plain worked out for me.
For what it’s worth, I chose to keep the Safariland 6378 and sold the others to get more 6378s, for my 1911 and for my Glocks with the TLR-1 attached. I can’t give a more sincere endorsement.
