Comfortable, Reliable Concealment

Massaro Holster Works was born of frustration. Founder and Inventor, Eddie Massaro couldn’t find a holster that he enjoyed wearing all day, every day. A mechanical engineer, Eddie dug in, did the research, and handcrafted the first American Purebred in his garage. Today, our flagship IWB holster is a popular pick among concealed-carry enthusiasts! Recently, in cooperation with Dave Spaulding, renowned firearms instructor, Eddie developed the S.P.E.E.D. OWB Concealed Carry Holster. In addition to the American Purebred and the S.P.E.E.D. Holster, Massaro offers a line of add ons and accessories.

Very Comfortable

I got one of the first holsters hot off the press for my Shield. I absolutely love it. Very comfortable, and unnoticeable. You can honestly forget that you are wearing it.

American Purebred

Best holster I’ve yet to try out. Haven’t had it long, but as of now, the purebred is my go to EDC iwb holster

– Michael Lewis


What can I say, this is EASILY the most comfortable holster I’ve ever worn. I’m in a wheelchair so trying to find something for me has been a huge issue. Well, I found it.. Holster has great retention and the clips are stout so it’s not going anywhere.. Overall A++++ and I will be a customer for life!!!

Best Holster on the Market!

I love this holster! The best holster to ever hit the market! I can even wear it with yoga pants and leggings! This is truly a holster that holds up what a woman needs!!!

– Ariol Dunlap

I LOVE this Holster

As someone who has several “great holsters” laying in the gun closet that just aren’t what they were cracked up to be.By simply changing the position of the holster I can carry cross draw at 10 or I can carry it at five at the small of my back or anywhere between. This thing is also very comfortable. There’s no pinching, binding or chafing with it. Give this holster a try. I promise that you will not be disappointed.

Great for Women!

Brilliant design! Ultra comfortable. Great for women as the design doesn’t require a belt. The backing pad has grip, doesn’t pinch or hurt. Moves with you and has no noticeable print.
