Yes, it is a cheaper made gun. The Rohm guns were the original "Saturday Night Specials", made cheap and sold cheap, from $9.95 way up to $19.95. They have about zero shooter interest, being short barrelled, not very accurate and with horrible sights and trigger pulls. They also have no collector interest.
If the gun has some sentimental value, keep it for that reason. If you want to shoot it, do so, but if anything breaks, it will probably not be worth fixing.
