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.

Re: Handgun Trigger Reach Measurements

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.

I will re-measure with the slack taken up.

This is a great idea and could be enhanced with the info that someone (that past away) collected and published on the old mouseguns site.

This will get you to several sources of said info.

http://www.google.com/search?sourcei....0.1Hb3ylI7EQY

Trigger reach is a very import piece of data... at least for me.

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

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”

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

Walther PPQ with small backstrap in place:

2.83" - trigger and safety blade fully extended
2.54" - slack removed and before firing pressure

Note: The difference in this case is more akin to a two-stage trigger than simply "slack," and the longer figure determines whether a person is comfortable with the reach on this firearm.

Wow. I didn't know the length on the PPQ was longer than a Glock.

I don't think it is. Glock says G19 Gen4 trigger reach is 2.73", but... That measurement appears to be based upon where the trigger exits from the receiver, not where you put your finger on it. As the trigger curves forward from there, the actual reach with your trigger finger is longer than the official measurement.

The actual measurement with my calipers depends upon from where on the trigger you measure - just down from the top of the safety blade it's 2.91," with slack.

Call it 2.76" slack out.

As for the intangible "feel," the PPQ feels much shorter and more manageable.
