NEITHER. Go to www.stealthdefenseholsters.com and read/ watch their videos. As a happy user, I can tell you almost any kind of clothing can be worn with maximum comfort and minimum if any, printing.
Don't expect any quickness from aliengear, they say 4-6 weeks for shipping and they use every bit of it apparently. I'm on week 5 waiting and not sleeping at night
I'm leaning towards aliengear, but I'm not in a big hurry. I just carry my other .380, a Ruger LCP in my pocket. I'm also looking for other handguns I own, also.
Hi. my first post here but these are all I buy now http://www.ozarksholstercompany.com/ I have both the IWB he calls it (Handmade Hybrid IWB Holster) and his OWB (OWB Kydex) and love them both. I carry my Sig 239 IWB every day and use the Kydex when I have a jacket on. It is a one man shop guys name is Dustin and his price is fair and he is quick I normally get my goods in about 10 days from when I order. I just looked and he sells both for your glock 42. He has 4 or 5 different designs as well as knife and mag holders plus he will do custom work for you (I have not done any with him)
I kept reading Lots of good things on the Sig forum about his holsters so I gave him a shot, now they are all I get and they are guaranteed for life. Anyway if you want a good quality rig that doesn't cost much this is the way to go.
