I don't know why someone would think that lead bullets in .40 are not that common - I've been shooting them for about a decade, including my Glock. I started with 175 grain SWC's and now use poly-coated 180 grain RNFP's. To the extent lead bullets in .40 are "not that common," it is because many of those reloading .40 are shooting USPSA Limited and want high velocity and low smoke. I find the poly-coating achieves both objectives at less cost than jacketed bullets.

THAT said, I second the recommendation for a good used S&W. They are becoming a glut on the market as PD's replace them with new models. Around here, the preference is for SIG, S&W M&P's and Glock, in that order. They all had S&W Third-Gens prior to that change and those guns are now on the used market.

Take advantage of the opportunity to get a probably little-used pistol for a good price.
