If you want gun of this type to use I would look at offerings from Sig Sauer. The 10xx series has not been made for many years, therefore, certain parts are most likely impossible to get. Original magazines are probably very expensive to buy. To add insult to injury price for one in excellent condition is not far off the price of new Sig Sauer 10x25.
If you want large, nicely made S&W vintage pistol I would look at Model 645 .45ACP. Ammo is cheaper to buy and the pistol will last longer if shot on regular basis.
