i started out carrying makarov (9 x 18) but i prefered the 1911.
MY 1911 would move around on me a lot.
I found the solution to the problem is to buy a good holster and a good gunbelt.
I bought a comp-tac brand c-tac IWB holster for CCW and it works great.
their site is www.comp-tac.com
The belt I bought is an IWB. It is leather and is about 1/4 inch thick x 1-1/2 wide. This ANCHORS the gun and holster in place. I bought the belt at the location where I went to for my CCW classes.
I now carry my 1911 full sized pistol where ever I go 24/7.
