Would it be possible to run a sls hood on the 6354do?Looks pretty easy but i could be wrong. Or maybe cut out the top of a 7360 holster?
You would not be able to cut off the 7360 holster to clearance for the red dot. The area you need to cut is the area that holds the ALS bar in place with a screw. (I don't believe there is anything else holding the ALS bar in place on the new models. 63XX and 73XX models.) If you have an older ALS/SLS model, (i think the serial prefix is 62XX like the SLS only holsters) you might be able to cut the top due to the way the ALS bar locks into the holster body. But as far as I know, those older ALS/ SLS models were discontinued.
Slapping an SLS hood on a 6354DO looks doable, but the problem you will run into is that the two upper most mount holes on the ALS lever side of the holster are spaced wrong and are actually for the holster shank. If you can get the SLS hood to fit, you still have the issue of not being able to mount a holster shank with out modifying the holster body. If that is the route you are looking to go, I would wait another month or two for the duty style 6354DO series to hit the market. That time frame is the projected time frame that Safariland's customer service gave me about 2 weeks ago.
Having said all of that, if you do give it a go with either choice, post up so we can see the results.
