OK, for the Glock 42, according to Uncle Mike's fitment chart on the Uncle Mike's Web site I need a size 1, or do I need a size 10?

I dont know what size you should get but I can tell you that this holster has a very thin belt clip. I would spend a bit more and go for a holster with a metal clip like this http://www.amazon.com/OUTBAGS-LOB3S-G42-BLACK-RIGHT-Genuine-Handcrafted/dp/B00KQ3BRMG/ref=sr_1_13?s=sporting-goods&ie=UTF8&qid=1421798909&sr=1-13&keywords=glock+42+holster

Go to "Uncle Mike's Holster sizing guide" (search for that phrase), and enter the gun brand and model, that you wish to fit. Get the information from the Horse's mouth.

Like John said, if you use a size 6, it will be snug. I would look around. Go to your local gun shop. Most will let you go through the holsters to see what works for you; at least mine did.

Not sure, they're sizing is somewhat different. I have a size 15 for a Glock 23. Check Uncle Mikes web site for correct configurations.

You would need size 3. I own that one and it is correct for that sized gun.

Yes, I bought it for my Glock 27 and they are the same size. It will fit perfectly

Allegedly the 9 and 40 versions are the same size. I have a 9 standard size, my brother has a 9 with the thumb safety. It fits. Like all things, mileage may vary. It was meant to be a "universal" m&p; holster to fit most if not all variants. If you don't like it, sell it, return it, etc.....from what I hear Amazon is pretty good about returns, but for what it's worth, I will keep mine because I like it. Get a STURDY belt. It's heavy with the gun, holster, and rounds in it.

@OP: Yes, they will work on the Glock 27. Just make sure you select the Glock sights in the drop down - not the Springfield XD series.@Rich & @Edwin: Glock 42 and 43 front sights are the same size as the other Glock sights. The slide is more narrow than the double stack pistols, so while a standard Glock rear will slide into the G42/43 frame, they would hang off the slide on both ends. (FYI - I sat through a G43 demonstration sponsored by Glock and got the information straight from one of the engineers on the design team.) There are plenty of G42/43 sights being made now, and a complete list can be seen here: http://www.gunsholstersandgear.com/glock-43-sights/ @OP: Yes, they will work on the Glock 27.

These are not listed for a glock 27.There is another set for the 27. I have these on my 22 and the other set on my 27. Why they dont fit i do not know. But i would trust the manufacturer.

I don't know about glocks. Check their website, they should have a matrix showing what fits what.

In reading the rest of the reviews I would say yes. It fit my glock 27 perfect. http://www.amazon.com/gp/aw/cr/B000KOUDQC/ref=mw_dp_cr?vs=1

This specific one will not fit the 42. You need to search on Amazon or the company site for the one that fits your Glock model.

Go to Uncle Mike's holsters and they have a chart that shows what holster to buy for a specific type pistol based on caliber, barrel length, etc.

YES, I just purchased a G41 and it does fit without any adjustment. The Glock 41 slide is the same width and length of a 34/35 slide. The trigger guard is also the same width on all 3 models. There may be just the slightest bit of rubbing in the frame area where your off hand thumb would rest in a "thumbs forward" hold, but I'm not that picky if it causes a wear mark.

Size 10 that I ordered, fits the .40 and 9mm shield. Do not know the answer to your question. You can always go to the Uncle Mike web page and e:mail them.
