Hi,
For some reason there seems to be a trend of thought that one can only shoot "really well" with one particular gun. I would like to disagree, and people that compete in pin-shooting and IDPA with multiple guns are likely to understand me and agree.
In a pin-shooting match I will start off with my 1911 (Pistol class) then shoot with my S&W 586 (revolver) and immediately proceed to shoot with my HP browning (9mm tip-over)and then back to whatever is the elim class in that particular day.
To those unfamiliar, when you shoot pins, you need to drive them off a 1M table - off the back of the table, so the real target you need to hit is the center of gravity of a bowling pin, which is un marked. you shoot from 8 meters and if you want to be competitive you need to train to shoot VERY fast and VERY accurately. added to that is the adrenaline rush of the competition, which affects you in a manner most similar to that of an encounter. one would think that a person will excell only with one particular gun, not so; it is clear that those who learn well and practice well end up shooting well, regardless of the particular weapon and class they are shooting. to give yo some idea, in the pistol class (usually shot with 0.45,10mm,9x21,0.40) you have 5 pins to knock, and a time above 6 seconds is not bad but wont get you anywhere close to the top, because for that you need to be below 5 seconds (national record is 3.53 seconds) with a 6 shot revolver you have 8 pins,( must do a manual reload- no speed loaders) and a good time is 10 seconds or less (including the reload)
Another example is a local chap who for many years ranked amongst the country's top IPSC shooters (national team), for those he had a couple of the space age guns that IPSC chaps love, in 9x21 and 0.45. Great competition pieces, not so much as carry guns. He always carried a Glock 0.40, and although he certainly practiced with it less than he did with his match guns, he could still shoot extremely well with it.
My point is that I believe that you do not necessary have to shoot mostly with one gun in order to shoot well, and that as long as you shoot well with the one you carry, and you practice with it enough to be proficient with it to the point that you are comfortable, there is nothing wrong with shooting more with other guns.
Brgds,
