Welcome to the Forum, Andy59.
If by "combat grips" you mean finger groove wooden grips that have the filler behind the trigger guard, the answer is No.
The modified M25-2 in this post, picture # 11, is wearing round butt N frame combat grips:
Jovino model 25-2 ? You decide.
I believe the 3 1/2 and 5" barrel M27s in that era all had Magna grips as standard. Not sure about the longer barreled ones.
Please post pictures.
