IMHO tungsten sleeve was just a waste of time and money. It weakens your barrel by trimming it to thinner metal." that space between the barrel and the tungsten???". I don't see the logic were people use tungsten to put weight to the front yet they lighten up the front slide? Duh!
I prefer short to mid. It's by feel. Not all have same way of pulling the trigger, some are faster in stock trigger short than dose expensive after market were the function are all the same.
I have the regular tripp 10mm mags. I have aluminum wide but for no gap. I change my magwell to WITH gap. if you have no use of it and willing to part kindly let me know the cost if I can afford.
