Handgun Trigger Reach Measurements

One measurement I found missing in the manufacturer's spec sheet for handguns is the Trigger Reach/Length of Pull (LOP). The distance from the face of the trigger to the rear of the grip. So, I thought maybe we could compile some data for those that are interested. I took out my calipers and measured some of my handguns and found others on the internet. All measurements in inches.

Glock 23 Gen3 = 2.82
Glock 19 Gen4 = 2.73
S&W M&P9 (Med) = 2.63
Ruger SR9 = 2.68
Walther PPS = 2.71
Sig P239 (DA) = 2.87
1911 (w/Long Trigger) = 2.75
Ruger LCP = 2.44

Let's continue to add more data. For DA/SA pistols, let's measure it in DA mode.
 
How did you take the measurements?
Did you take into account the width of the grips?
Or use a caliper from trigger to back strap?
 
Just interested in the measurement from the face of the trigger to the rear of the backstrap with calipers. There seems to be alot of measurements for the width of the grips but not so much for the LOP.
 
Good idea. One problem: a thick grip will make a trigger pull .1" shrter feel longer, as the hand is more 'full'.

Try to get cz75 and cz97 measurements. Those felt longer than any except sig p226 (w/o thin grips or the new shspe to backstrap area). Baby eagle is up there too.

Could you guys add measurement for LOP when all slack has been taken up if applicable - like Glock or M&P triggers?
Width would be nice to have, too.
I will measure some of mine when I get home.

Format Maybe,
Make/Model - Width - Trigger face to backstrap - Trigger face w/o slack to backstrap.
 
It is an important dimension and the grip circumference does have an impact on the effective distance. This is also why the distance is adjustable on quality pistols.
 
From having had a large number of different guns over the years I know that this sort of measurement is useful in only a most GENERAL way and arguably has limited value.

The width of the grip (including the grip panels installed, and which may be changed), the depth of the grip (the distance between front- and back-strap), how high shooter is able to move the hand UP on the grip column (under a beavertail, if there is one worth mentioning), and even the WIDTH of the trigger are all factors that affect the USABILITY of a given trigger for a given gun.

(Other factors, such as takeup, and how the trigger moves -- pivoting on a pin, or moving back, as with a 1911 -- can also affect how the trigger finger is able to use/access the trigger, despite measured dimensions.)

Unless you can somehow take most of these factors into consideration, the dimensions being mentioned are numbers offered in a vacuum. Two guns with identical lengths of pull measurements could feel and function quite differently in the same hand...
 
Some measurements.

All measurements taken with initial trigger slack removed. In other words the slack/free-play of the trigger is removed prior to measurement. Measurement is from the trigger face that provides the least reach distance to the web area of the hand of the backstrap. Additionally grip safety is press in.

DA = Double Action
SA = Single Action
( ) = Additional info: Caliber, SAO=Single Action Only, DS=Double Stack, SS= Single Stack


S&W 745 (45ACP, SAO, SS)= 2.47”

Colt Gold Cup w/aftermarket short wide trigger (45ACP, SAO, SS)= 2.53”

Walther P5 (9mm, SS)= DA 2.81”, SA 2.43”

Ruger P89 (9mm, DS)= DA 2.86”, SA 2.53”

High Standard Victor 5.5” (22LR, SAO, SS)= 2.56”

Beretta 21A (25ACP, SS)= DA 2.84”, SA 2.33”

Glock 19C Gen3 (compensated) (9mm, DS)= DA 2.66”

I'd like to know what the trigger reach is on K, L and N frame revolvers, and also the s&w Governor. Also, Pitt, I find it hard to believe that the P239 has a longer trigger reach then the double stack P228, which as a trigger reach of 2.780 inches. http://www.gunblast.com/Sig-MK25-M11A1.htm

That M11A1 has the reduced or short reach trigger. The MK25 has the regular/original trigger with that long 2.9 inch reach.
