Is it a 15, or a 15-2?
What barrel length?
FWIW I have had my 6" VH for ever & still like it!
The only problem common to them is a light primer strike in D/A mode. If you reload keep this in mind when picking primers. Also check the D/A cocking if you replace the grips as the grip screw length is critical & some aftermarket grip screws are too long & bind up the D/A action.
