Striker-Fire??

[Lonestar]

I have been looking at a lot of autos trying to make a decision and finding great variations in trigger actions although they are spec'd using the same terminology.  I will try to describe what I have found...

Standard striker fire (GLOCK, XD, M&P) I would consider autocock/SA.  All of them cock once slide is racked either to load, or by firing, but do not allow second strike if misfire.  Once cocked, the striker remains cocked until trigger is pulled.  More detail explanation is contained in Why Glocks are NOT Double Action.

DA/SA (Kel Tec, Ruger LCP), does not cock after racking slide to load.  First pull is DA, but it does not allow second strike if misfire.  I was told remaining shots were autocock/SA, but am not sure as I did not fire any rounds, for all I know every trigger pull could be DA after racking slide.

SA/DA (Taurus 24/7, Millinneum), striker/hammer cock once slide is racked either to load or by firing, DA is allowed after misfire/dry fire, however there is no way to decock after loading round.

DA (SW99, P99, PX4, FNP40) are true DA. Alll of them cock once slide is racked, but allow decock.  First trigger pull then would be DA followed by autocock/SA, which is technically I guess DA/SA, except it does allow second strike capability if misfire.  The only difference with the 99's is they are enclosed striker fire while the other 2 have hammer pull allowing manual cocking without racking slide for SA first shot. The 99's do have striker witness hole to give visual of striker position.

DAO (FNP40) One version of the FNP40 is DAO, which I did not see, but with my expereince with the DA/SA model, I could see with a enclosed hammer how it could be a true autoload/DAO auto.

Think I narrowed it down to the SN99 or the FNP40.  I like the fact the striker is enclosed on the SN99, + its about $100 less.  Althought the FNP has slightly larger mag (14 vs 12) and slightly larger/comfortable grip.


I guess for a true failsafe, a revolver wins hands down, not only do you have ability to restrike, it automaticaly loads a new round encase of any primer/cartridge failures.
