Owners manual says to replace every 2500 rds.
Seems like short lifespan for this assembly.
Anybody have a larger round count then 2500 without changing?

I have never kept round count on any of my guns in the past and probably will not start now.

Our rental gun has roughly 20K on it.. no issues yet.

I keep track of all rounds fired in my pistols in gun log, it's $1.99, easy to use app for your smart phone. It is very good for inventorying all of your guns.

I plan on changing it every 2,500 rounds.

2500 is not very many rounds but it's a small gun, SIG is covering their butt with that maintenance interval recommendation.

As noted, it's an inexpensive insurance policy to keep your weapon from beating itself to death.

Sig sells the RSA for $29. Presently out of stock. May be available through other suppliers.

Grab one or some, and have one IF needed on hand.
