well i took the uncle mike's out of the package last night and it is VERY different from the fobus. i only had time for a quick inspection last night and thought i would post some initial observations and impressions.
Observations:
it is a paddle model for my sig 220/226 and belt retention is by a undercut block on the paddle which secures under the belt. the big thing is that the holster pouch is a one piece molding which is folded over the front of the gun and wrap around to the back. two screws, with compression tubing, join the pouch at the rear but leave the back open. the mouth of the pouch flares out and the front is cut down to below the ejection port.
there are a lot of adjustments available due to the construction using screws rather than rivets.
1. ride height and cant adjust (it came in vertical draw and low ride) throught 2 holes in the pouch and 4 holes in the paddle
2. the retention block is adjustable, 2 holes in paddle, for belt width
3. trigger guard retention/holster tension are adjusted, independently, by the upper and lower rear screws respectively
the pouch tension/retention can be adjusted from nothing (like a quick draw rig) to somthing that will hold the gun upside down and allow shaking (almost as secure as the fobus). retention is through symmetrical moldings into the triggerguard.
Impressions (i didn't take measurements, they are just guesses):
1. the kydex used in the UM holster is thicker (50%) than the fobus but is also much heavier (x 2+)
2. the UM is prettier with less excess material and more detailed molding
3. the UM is less stable on the belt with it's single point retention than the fobus wide spread fingers/ledge
4. i didn't find that the holster "leaned out", but the holster does "stick out" more due to the flaring of the holster mouth
5. the UM retains the gun securely, when adjusted/screwed down, but lacks the "anti-snatch" feature of the fobus.
i can see the UM's as a great competition holster but feel that the fobus is a better carry piece. at the price, they are both great buys and lightyears ahead of the "one size fits all" leather/nylon pouches.
sorry about the lenght, i tried ti distill it down as much as i could.
