Unfortunately, it doesn't come in non+P.
However, you have some other choices in non+P Winchester ammunition. They offer a Super-X Silver Tip 110gr hollow point, although I've always felt that was just a bit light for my taste. On the other hand, it's not that much lighter than the Federal Nyclad standard pressure Chief's Load 125gr HP, which reportedly performed fine in the 2" snubbies for which it was renamed.
In the newer USA line Winchester lists a 125gr JHP & a 125gr JSP for practice. The odd thing is that the JHP is rated at exactly the same velocity (945fps) out of a 4" Vented test barrel as their 125gr +P JHP and their 125gr Silver Tip +P. The Symbol number is USA38JSP, so you might want to check it out at a local store and see if the catalog forgot to list the +P rating. The USA38SP is a standard pressure 125gr JSP, and it's rated for much less velocity (850fps), which makes me wonder if the catalog data for the JHP is simply lacking the +P rating??
These figures will give you a headache. Personally, in my older 649 Bodyguard, I always practiced with standard pressure ammunition, and carried the +P version of the same load. Occasionally, I'd fire some +P through it just to cycle the older carry rounds out. The steel J-frames didn't seem to mind some occasional +P. The +P pressures of the major manufacturers weren't all that much above and beyond standard SAAMI specs. I knew people restricted to S&W model 60's for off duty, and restricted to state contract 110gr +P+ ammunition, back when S&W wouldn't tell the public whether they would warranty the 60 for +P use. I'm sure it accelerated the wear & tear on the 60's, though ...
The 130gr SXT round is actually rated at a slightly lower velocity than the 125gr Silver Tip +P ... 925fps vs 945fps ... both out of 4" Vented test barrels, if it interests you ... but the SXT design has been advertised as having been tweaked by Winchester to perform at lower velocities. It's a better bullet ... but I'd want to see results that define what that means out of my 2" ...
Since the LHP +P has established a fairly consistent performance record out of 2" barrels, and generally shoots to point of aim in most snubnose revolvers, that's my preferred round for carry. But, we now have access online to a lot of test results for a lot of the newer ammunition, so you ought to be able select something that gives you confidence in your cherished 36 ... Just limit your practice to standard pressure ammunition, and it wouldn't hurt to have an armorer or gunsmith give it a quick inspection every few years.
Of course, you could always retire your little 36 to the safe, to be brought out for special occasions, and replace it with a 642-1. That little aluminum J-frame is rated for a lifetime of +P use, isn't restricted to any particular bullet type, and is really convenient for pocket carry. I retired my 649 that way, but still take it out once in a while. There's just a great selection of J-frames to choose from nowadays ...
