3913 Recoil Spring

A simple question about spring length really went off the rails with the two of you.... Goodness!
 
It seems to me that you might be the one being dismissive of other's opinions and knowledge. I think my question of "how many handguns have you encountered with many 10s of 1000s of rounds?" is relevant to the conversation. Your response is that I don't respect your 37 years of experience. You seem to be taking offense to any opinion other than your own. If it's considered relevant, I have 35 years of experience in shooting, reloading, gunsmithing and competition. I've been involved in parts design and fabrication for TK Custom, Apex Tactical, CZ Custom, MBX Extreme, Langdon Tactical and my own HearthCo Moonclips.
With all due respect to your opinion, broad adversarial generalizations on either side would seem to be unnecessarily antagonistic and OFF TOPIC. If you dont have experience with SW Aluminum framed pistols, maybe at least try to stay ON TOPIC.
 
Aluminum guns are meant to be shot little and carried much.

Early Colt Commander's were that way, but S&W's aluminum receivers will, with proper maintenance, survive many tens of thousands of rounds of full power ammo.

Remember the old Miller Lite commercial?

Less filling!

Tastes great!

You are both correct.

BITD, even S&W admitted that the alloy framed guns would not likely be able to achieve the round counts of the steel framed guns, all things being equal.

Of course, in the real world, all things are seldom equal...

Maintain an alloy framed gun and it can achieve very high round counts.

Abuse a steel framed gun and it will fail early.

I was in the motorcycle business for 40 years and it is the same thing.

Harleys, Hondas, Triumphs, Yamahas, BSAs, Kawasakis, Nortons, Suzukis, BMWs, Moto Guzzis, et al.

Sedate street cruisers and all-out competition racers.

I sold, rode, and serviced them all.

Maintain them and they will last.

Abuse them and they will fail.

There are numerous 3rd Gen owners and shooters, including S&W factory trained LE armorers who disagree. Some have fired thousands of rounds out of their alloy framed guns with no issues. Proper maintenance is the key.
I concur.
What may help people to understand is that the "peening problem" is not really a problem. The wear decreases exponentially and stops completely at a point which is still fully functional and safe. So it is and has been on all of my 3rd gen aluminum framed guns.

My authority for this statement is our now departed comrade 18DAI who was quite the recognized authority and advocate for these pistols here on our forum and in the Greensboro area where he served as a police shooting instructor among other things for many years. He is one whom I have found to be consistently correct since first reading him in 2005 and ever since.

You only need to know this if you are new to these guns and you purchase one which has been unfired. When you clean it for the first time you may be surprised and concerned fearing the continuation of that level of wear. BTW this principle of expected acceptable wear also applies to flame cutting of certain S&W revolvers.

Best Regards to You All,

Does anyone know the correct spring length for the 3913? The one I took out of the gun is 3-7/8" and the one from Midway is 4-5/8".
.
To answer your specific question:

The new Midway #349212 recoil spring I have, coated in light green paint, (pkg dated 120914), which should be S&W #100950000, measures ~4.41" long.

The new Wolff #47515 recoil spring (Midway #391128) I have (pkg dated 101614), which is Wolff's standard power (15#) replacement spring for the 3913, 6906 & more, measures ~4.70" long.

The two new Wolff #47517 recoil springs (Midway #362081) I have (pkg dated 100119), which is Wolff's extra power (17#) replacement spring for the 3913, 6906 & more, measures ~4.33" long

My 3914, 3914DAO & 3913TSW all have Wolff 47518 (18#) recoil springs in them because all of my 9x19 handloads are full power or +P power.
