Breaking the rules? Well...not really, but it does bend them a little. Two stage triggers have been used for many years by target shooters, especially rifle shooters where trigger control is so very important. Not so common with pistols but they are becoming very common in the top target pistols today. Two stage triggers will get you tens but you must know how to set them up correctly or they are worse than nothing. Lets assume, for example, that the regulations call for a min. two pound trigger The single stage trigger has one only clean pull-through before the sear let-off. This means that the shooter must exert two pounds of pressure on the firearm to get it to fire. Of course it is difficult to exert two pounds pressure on the gun without causing it to move on the target. Naturally it moves off center before the shot breaks. The less solidly the firearm is supported, the more it moves. If the trigger is jerked or the pressure is exerted quickly, the gun will move even more. The lighter the trigger, the less the gun will move. The lighter the trigger...the less the unwanted movement.The two stage trigger has two stages of movement before the sear disengages. Using the above example of a two pound trigger, the first stage will take perhaps one and a half pounds and then come to a distinct stop. The stop can easily be felt by the shooter and he can hold this pressure for an indefinite period of time. When the sight picture is right all he needs to do is squeeze off the remaining half pound for it to fire. Effectively he is shooting with a half pound trigger and he has a distinct advantage over his neighbour who may have a single stage. It is totally legal because the sum of the first and second stages equals the allowable pull weight. Some are factory set first and second stage weight and therefore have a fixed ratio. On others only the total weight may be adjusted. The best triggers have independently adjustable first and second stage weights and can still be made to total the pull weight required by the regulations. This is the trigger you should look for. The Walther GSP trigger is probably the best example of an excellent fully adjustable two stage. It is a "trigger in a drawer". The complete trigger is quickly removable from the frame for easy adjustment and cleaning. They come factory set at 800g/560g which means 800g on the first stage and 560g on the second stage...total 1360g. If you have the two-gun combination .32 and .22lr. you can leave the above weight settings on the trigger for both competitions, standard and centerfire. You don’t need two triggers!! This way you only need to purchase one trigger and you get used to only one for both courses of fire. The design intends you to use one trigger in both .22 and .32 guns. Of course the total weight on your trigger for the .22 course will be 1360g instead of the 1000g required by the regulations but remember you are really squeezing off only 560g. The GSP trigger is fully machined and beautifully simple in design. You will only need to take it out and compare it with the manual to figure out exactly how it works. Adjustments can be tricky, especially if you do not understand the geometry of it. Take some time to sort it out and the trigger can be set to any feel that you like, the combinations are limitless.
