No...this is DEFINITELY NOT a *who do you think makes the best blahblahblah holster*... Its a question on *preference* of a particular *feature* that seems to be in demand and/or gaining popularity, and I'm curious as to why... Thumb breaks holsters, be it a IWB or OWB holster, whilst carrying a 1911. With the safety features of a 1911 (thumb switch must be off and grip safety must be depressed before the gun will fire...) I'm curious as to why people seem to want thumb breaks. Even if carrying in Condition 1, the gun is really quite safe, won't discharge if dropped (unless you've done alot of "COUGH" *custom* "COUGH" trigger work with a Dremel on your own) and a well-made holster will provide the proper retention via friction for an OWB holster, and a thumb break on a IWB seems redundant if the reason is to prevent a gun grab, because, when properly concealed, no-one is supposed to be able to tell that there is a gun under your shirt to grab. I personally can't see a reason for a thumb break on a IWB as its yet another step in drawing the weapon that you need to be mindful of, and you've already got enough to worry about in getting your cover garment cleared so that you can draw if, God forbid, its a life-or-death situation. Why add a thumb break to the list of possible snag points? On a OWB, I can understand the reasoning for a bit more safety from a gun grab, especially when the firearm is being OC'd. Then again, you can carry OWB with a cover garment, and if properly concealed, the chances of a gun-grab are practically nil, because if a perp can't *see* it, how does he know to *grab* it? So...do you prefer thumb breaks on your 1911 rigs, either IWB or OWB, and why? This question is for CIVILIAN CARRY, not LEO, not Security Guard, not Prison Guard, etc... The question is for the typical man-on-the-street civilian exercising his 2A rights.
