Just so you will know, the cutout at the base of the lockbar on the TiRIL Military measures 0.048" thick. The liner/lockbar on the regular Military measures 0.048" thick. One is titanium, one is steel. Guess which is likely to be stronger. 
The old 440V Millie with one partial liner was strong enough to stand up to anything someone with two active brain cells is likely to dish out. Any of the others will be as well. Choose by steel and handle preference.
I don't believe in safe queens, only in pre-need replacements.
