I've had mine for a while now. Quality construction and materials at a fair price.
The downside for me is that it just isn't as comfortable as I thought it would be.
That may be due to my 36" waist. It really spreads the weight of the pistol out.
They have a trial period with full refund if not satisfied.
I own both, but for me I like the 2.0 when carrying my 1911 because the 3.0 seems to slide back more (even with the belt clenched very tight). I don't seem to have this issue with the 2.0 or when I use my 3.0 with my XDS (which weights less). It may be because I carry at 3 o clock but that is what is most comfortable for me.I really like the galco also, but I dont think they make one for my gun unfortunately.
Im curious as to the difference between the alien gear 2.0 and 3.0? I can look at their website, but Im asking from those who actually own both.
